proxy: add a free function for the options's pointers
When we duplicate a user-provided options struct, we're stuck with freeing the
url in it. In case we add stuff to the proxy struct, let's add a function in
which to put the logic.

Clear the remote_ref_name buffer in git_push_update_tips()
If fetch_spec was a non-pattern, and it is not the first iteration of push_status vector, then git_refspec_transform would result in the new value appended via git_buf_puts to the previous iteration value.
Forcibly clearing the buffer on each iteration to prevent this behavior.

signature: don't leave a dangling pointer to the strings on parse failure
If the signature is invalid but we detect that after allocating the strings, we
free them. We however leave that pointer dangling in the structure the caller
gave us, which can lead to double-free.
Set these pointers to `NULL` after freeing their memory to avoid this.

ignore: honor case insensitivity for negative ignores
When computing negative ignores, we throw away any rule which does not
undo a previous rule to optimize. But on case insensitive file systems,
we need to keep in mind that a negative ignore can also undo a previous
rule with different case, which we did not yet honor while determining
whether a rule undoes a previous one. So in the following example, we
fail to unignore the "/Case" directory:
/case
!/Case
Make both paths checking whether a plain- or wildcard-based rule undo a
previous rule aware of case-insensitivity. This fixes the described
issue.

sha1_position: convert do-while to while
If we enter the sha1_position() function with "lo == hi",
we have no elements. But the do-while loop means that we'll
enter the loop body once anyway, picking "mi" at that same
value and comparing nonsense to our desired key. This is
unlikely to match in practice, but we still shouldn't be
looking at the memory in the first place.
This bug is inherited from git.git; it was fixed there in
e01580cfe01526ec2c4eb4899f776a82ade7e0e1.

ignore: keep negative rules containing wildcards
Ignore rules allow for reverting a previously ignored rule by prefixing
it with an exclamation mark. As such, a negative rule can only override
previously ignored files. While computing all ignore patterns, we try to
use this fact to optimize away some negative rules which do not override
any previous patterns, as they won't change the outcome anyway.
In some cases, though, this optimization causes us to get the actual
ignores wrong for some files. This may happen whenever the pattern
contains a wildcard, as we are unable to reason about whether a pattern
overrides a previous pattern in a sane way. This happens for example in
the case where a gitignore file contains "*.c" and "!src/*.c", where we
wouldn't un-ignore files inside of the "src/" subdirectory.
In this case, the first solution coming to mind may be to just strip the
"src/" prefix and simply compare the basenames. While that would work
here, it would stop working as soon as the basename pattern itself is
different, like for example with "*x.c" and "!src/*.c. As such, we
settle for the easier fix of just not optimizing away rules that contain
a wildcard.

index: error out on unreasonable prefix-compressed path lengths
When computing the complete path length from the encoded
prefix-compressed path, we end up just allocating the complete path
without ever checking what the encoded path length actually is. This can
easily lead to a denial of service by just encoding an unreasonable long
path name inside of the index. Git already enforces a maximum path
length of 4096 bytes. As we also have that enforcement ready in some
places, just make sure that the resulting path is smaller than
GIT_PATH_MAX.

index: fix out-of-bounds read with invalid index entry prefix length
The index format in version 4 has prefix-compressed entries, where every
index entry can compress its path by using a path prefix of the previous
entry. Since implmenting support for this index format version in commit
5625d86b9 (index: support index v4, 2016-05-17), though, we do not
correctly verify that the prefix length that we want to reuse is
actually smaller or equal to the amount of characters than the length of
the previous index entry's path. This can lead to a an integer underflow
and subsequently to an out-of-bounds read.
Fix this by verifying that the prefix is actually smaller than the
previous entry's path length.

index: convert `read_entry` to return entry size via an out-param
The function `read_entry` does not conform to our usual coding style of
returning stuff via the out parameter and to use the return value for
reporting errors. Due to most of our code conforming to that pattern, it
has become quite natural for us to actually return `-1` in case there is
any error, which has also slipped in with commit 5625d86b9 (index:
support index v4, 2016-05-17). As the function returns an `size_t` only,
though, the return value is wrapped around, causing the caller of
`read_tree` to continue with an invalid index entry. Ultimately, this
can lead to a double-free.
Improve code and fix the bug by converting the function to return the
index entry size via an out parameter and only using the return value to
indicate errors.

cmake: fix linker error with dbghelper library
When the MSVC_CRTDBG option is set by the developer, we will link in the
dbghelper library to enable memory lead detection in MSVC projects. We
are doing so by adding it to the variable `CMAKE_C_STANDARD_LIBRARIES`,
so that it is linked for every library and executable built by CMake.
But this causes our builds to fail with a linker error:
```
LINK: fatal error LNK1104: cannot open file 'advapi32.lib;Dbghelp.lib'
```
The issue here is that we are treating the variable as if it were an
array of libraries by setting it via the following command:
```
SET(CMAKE_C_STANDARD_LIBRARIES "${CMAKE_C_STANDARD_LIBRARIES}"
"Dbghelp.lib")
```
The generated build commands will then simply stringify the variable,
concatenating all the contained libraries with a ";". This causes the
observed linking failure.
To fix the issue, we should just treat the variabable as a simple
string. So instead of adding multiple members, we just add the
"Dbghelp.lib" library to the existing string, separated by a space
character.

cmake: disable optimization on debug builds
While our debug builds on MSVC platforms already tune the code optimizer
to aid debugging code, all the other platforms still use the default
optimization level. This makes it hard for developers on these platforms
to actually debug code while maintaining his sanity due to optimizations
like inlined code, elided variables etc.
To help this common use case, we can simply follow the MSVC example and
turn off code optimization with "-O0" for debug builds. While it would
be preferable to instead use "-Og" supported by more modern compilers,
we cannot guarantee that this level is available on all supported
platforms.

cmake: set "-D_DEBUG" on non-Windows platforms
In our code base, we have some occasions where we use the "_DEBUG"
preprocessor macro to enable additional code which should not be part of
release builds. While we define this flag on MSVC platforms, it is
guarded by the conditional `WIN32 AND NOT CYGWIN` on other platforms
since 19be3f9e6 (Improve MSVC compiler, linker flags, 2013-02-13). While
this condition can be fulfilled by the MSVC platform, it is never
encountered due to being part of the `ELSE` part of `IF (MSVC)`.
The intention of the conditional was most likely to avoid the
preprocessor macro on Cygwin platforms, but to include it on everthing
else. As such, the correct condition here would be `IF (NOT CYGWIN)`
instead. But digging a bit further, the condition is only ever used in
two places:
1. To skip the test in "core::structinit", which should also work on
Cygwin.
2. In "src/win32/git2.rc", where it is used to set additional file
flags. As this file is included in MSVC builds only, it cannot cause
any harm to set "_DEBUG" on Cygwin here.
As such, we can simply drop the conditional and always set "-D_DEBUG" on
all platforms.

tests: odb: add tests with multiple backends
Previous to pulling out and extending the fake backend, it was quite
cumbersome to write tests for very specific scenarios regarding
backends. But as we have made it more generic, it has become much easier
to do so. As such, this commit adds multiple tests for scenarios with
multiple backends for the ODB.
The changes also include a test for a very targeted scenario. When one
backend found a matching object via `read_prefix`, but the last backend
returns `GIT_ENOTFOUND` and when object hash verification is turned off,
we fail to reset the error code to `GIT_OK`. This causes us to segfault
later on, when doing a double-free on the returned object.

tests: odb: allow passing fake objects to the fake backend
Right now, the fake backend is quite restrained in the way how it
works: we pass it an OID which it is to return later as well as an error
code we want it to return. While this is sufficient for existing tests,
we can make the fake backend a little bit more generic in order to allow
us testing for additional scenarios.
To do so, we change the backend to not accept an error code and OID
which it is to return for queries, but instead a simple array of OIDs
with their respective blob contents. On each query, the fake backend
simply iterates through this array and returns the first matching
object.

odb_read_prefix: reset error in backends loop
When looking for an object by prefix, we query all the backends so that
we can ensure that there is no ambiguity. We need to reset the `error`
value between backends; otherwise the first backend may find an object
by prefix, but subsequent backends may not. If we do not reset the
`error` value then it will remain at `GIT_ENOTFOUND` and `read_prefix_1`
will fail, despite having actually found an object.

checkout: cope with untracked files in directory deletion
When deleting a directory during checkout, do not simply delete the
directory, since there may be untracked files. Instead, go into
the iterator and examine each file.
In the original code (the code with the faulty assumption), we look to
see if there's an index entry beneath the directory that we want to
remove. Eg, it looks to see if we have a workdir entry foo and an
index entry foo/bar.txt. If this is not the case, then the working
directory must have precious files in that directory. This part is okay.
The part that's not okay is if there is an index entry foo/bar.txt. It
just blows away the whole damned directory.
That's not cool.
Instead, by simply pushing the directory itself onto the stack and
iterating each entry, we will deal with the files one by one - whether
they're in the index (and can be force removed) or not (and are
precious).
The original code was a bad optimization, assuming that we didn't need
to git_iterator_advance_into if there was any index entry in the folder.
That's wrong - we could have optimized this iff all folder entries are
in the index.
Instead, we need to simply dig into the directory and analyze its
entries.

checkout: do not delete directories with untracked entries
If the `GIT_CHECKOUT_FORCE` flag is given to any of the `git_checkout`
invocations, we remove files which were previously staged. But while
doing so, we unfortunately also remove unstaged files in a directory
which contains at least one staged file, resulting in potential data
loss.
This commit adds two tests to verify behavior.

smart_protocol: fix parsing of server ACK responses
Fix ACK parsing in wait_while_ack() internal function. This patch
handles the case where multi_ack_detailed mode sends 'ready' ACKs. The
existing functionality would bail out too early, thus causing the
processing of the ensuing packfile to fail if/when 'ready' ACKs were
sent.

settings: rename `GIT_OPT_ENABLE_SYNCHRONOUS_OBJECT_CREATION`
Initially, the setting has been solely used to enable the use of
`fsync()` when creating objects. Since then, the use has been extended
to also cover references and index files. As the option is not yet part
of any release, we can still correct this by renaming the option to
something more sensible, indicating not only correlation to objects.
This commit renames the option to `GIT_OPT_ENABLE_FSYNC_GITDIR`. We also
move the variable from the object to repository source code.

buffer: use `git_buf_init` with length
The `git_buf_init` function has an optional length parameter, which will
cause the buffer to be initialized and allocated in one step. This can
be used instead of static initialization with `GIT_BUF_INIT` followed by
a `git_buf_grow`. This patch does so for two functions where it is
applicable.

buffer: return errors for `git_buf_init` and `git_buf_attach`
Both the `git_buf_init` and `git_buf_attach` functions may call
`git_buf_grow` in case they were given an allocation length as
parameter. As such, it is possible for these functions to fail when we
run out of memory. While it won't probably be used anytime soon, it does
indeed make sense to also record this fact by returning an error code
from both functions. As they belong to the internal API only, this
change does not break our interface.

buffer: consistently use `ENSURE_SIZE` to grow buffers on-demand
The `ENSURE_SIZE` macro can be used to grow a buffer if its currently
allocated size does not suffice a required target size. While most of
the code already uses this macro, the `git_buf_join` and `git_buf_join3`
functions do not yet use it. Due to the macro first checking whether we
have to grow the buffer at all, this has the benefit of saving a
function call when it is not needed. While this is nice to have, it will
probably not matter at all performance-wise -- instead, this only serves
for consistency across the code.

buffer: fix `ENSURE_SIZE` macro referencing wrong variable
While the `ENSURE_SIZE` macro gets a reference to both the buffer that
is to be resized and a new size, we were not consistently referencing
the passed buffer, but instead a variable `buf`, which is not passed in.
Funnily enough, we never noticed because our buffers seem to always be
named `buf` whenever the macro was being used.
Fix the macro by always using the passed-in buffer. While at it, add
braces around all mentions of passed-in variables as should be done with
macros to avoid subtle errors.

buffer: rely on `GITERR_OOM` set by `git_buf_try_grow`
The function `git_buf_try_grow` consistently calls `giterr_set_oom`
whenever growing the buffer fails due to insufficient memory being
available. So in fact, we do not have to do this ourselves when a call
to any buffer-growing function has failed due to an OOM situation. But
we still do so in two functions, which this patch cleans up.

sha1dc: do not use standard includes
The updated SHA1DC library allows us to use custom includes instead of
using standard includes. Due to requirements with cross-platform, we
provide some custom system includes files like for example the
"stdint.h" file on Win32. Because of this, we want to make sure to avoid
breaking cross-platform compatibility when SHA1DC is enabled.
To use the new mechanism, we can simply define
`SHA1DC_NO_STANDARD_INCLUDES`. Furthermore, we can specify custom
include files via two defines, which we now use to include our
"common.h" header.

openssl_stream: fix building with libressl
OpenSSL v1.1 has introduced a new way of initializing the library
without having to call various functions of different subsystems. In
libgit2, we have been adapting to that change with 88520151f
(openssl_stream: use new initialization function on OpenSSL version
>=1.1, 2017-04-07), where we added an #ifdef depending on the OpenSSL
version. This change broke building with libressl, though, which has not
changed its API in the same way.
Fix the issue by expanding the #ifdef condition to use the old way of
initializing with libressl.

tests: index::version: improve write test for index v4
The current write test does not trigger some edge-cases in the index
version 4 path compression code. Rewrite the test to start off the an
empty standard repository, creating index entries with interesting paths
itself. This allows for more fine-grained control over checked paths.
Furthermore, we now also verify that entry paths are actually
reconstructed correctly.

tests: index::version: verify we write compressed index entries
While we do have a test which checks whether a written index of version
4 has the correct version set, we do not check whether this actually
enables path compression for index entries. This commit adds a new test
by adding a number of index entries with equal path prefixes to the
index and subsequently flushing that to disk. With suffix compression
enabled by index version 4, only the last few bytes of these paths will
actually have to be written to the index, saving a lot of disk space.
For the test, differences are about an order of magnitude, allowing us
to easily verify without taking a deeper look at actual on-disk
contents.

tests: index::version: add test to read index version v4
While we have a simple test to determine whether we can write an index
of version 4, we never verified that we are able to read this kind of
index (and in fact, we were not able to do so). Add a new repository
which has an index of version 4. This repository is then read from a new
test.

index: verify we have enough space left when writing index entries
In our code writing index entries, we carry around a `disk_size`
representing how much memory we have in total and pass this value to
`git_encode_varint` to do bounds checks. This does not make much sense,
as at the time when passing on this variable it is already out of date.
Fix this by subtracting used memory from `disk_size` as we go along.
Furthermore, assert we've actually got enough space left to do the final
path memcpy.

index: fix shared prefix computation when writing index entry
When using compressed index entries, each entry's path is preceded by a
varint encoding how long the shared prefix with the previous index entry
actually is. We currently encode a length of `(path_len - same_len)`,
which is doubly wrong. First, `path_len` is already set to `path_len -
same_len` previously. Second, we want to encode the shared prefix rather
than the un-shared suffix length.
Fix this by using `same_len` as the varint value instead.

index: also sanity check entry size with compressed entries

required footer after reading an index entry, but this was only used for
uncompressed entries. Move the check down a bit so that it is executed
for both compressed and uncompressed index entries.

index: remove file-scope entry size macros
All index entry size computations are now performed in
`index_entry_size`. As such, we do not need the file-scope macros for
computing these sizes anymore. Remove them and move the `entry_size`
macro into the `index_entry_size` function.
