branch: refuse creating branches named 'HEAD'
Since a625b092c (branch: correctly reject refs/heads/{-dash,HEAD},
2017-11-14), which is included in v2.16.0, upstream git refuses to
create branches which are named HEAD to avoid ambiguity with the
symbolic HEAD reference. Adjust our own code to match that behaviour and
reject creating branches names HEAD.

refs: include " sorted " in our packed-refs header
This lets git know that we do in fact have written our packed-refs file
sorted (which is apparently not necessarily the case) and it can then use the
new-ish mmaped access which lets it avoid significant amounts of effort parsing
potentially large files to get to a single piece of data.

transports: local: fix memory leak in reference walk
Upon downloading the pack file, the local transport will iterate through
every reference using `git_reference_foreach`. The function is a bit
tricky though in that it requires the passed callback to free the
references, which does not currently happen.
Fix the memory leak by freeing all passed references in the callback.

cmake: add openssl to the private deps list when it's the TLS implementation
We might want OpenSSL to be the implementation for SHA-1 and/or TLS. If we only
want it for TLS (e.g. we're building with the collision-detecting SHA-1
implementation) then we did not indicate this to the systems including us a
static library.
Add OpenSSL to the list also during the TLS decision to make sure we say we
should link to it if we use it for TLS.

cmake: allow explicitly choosing SHA1 backend
Right now, if SHA1DC is disabled, the SHA1 backend is mostly chosen
based on which system libgit2 is being compiled on and which libraries
have been found. To give developers and distributions more choice,
enable them to request specific backends by passing in a
`-DSHA1_BACKEND=<BACKEND>` option instead. This completely replaces the
previous auto-selection.

diff_generate: avoid excessive stats of .gitattribute files
When generating a diff between two trees, for each file that is to be
diffed we have to determine whether it shall be treated as text or as
binary files. While git has heuristics to determine which kind of diff
to generate, users can also that default behaviour by setting or
unsetting the 'diff' attribute for specific files.
Because of that, we have to query gitattributes in order to determine
how to diff the current files. Instead of hitting the '.gitattributes'
file every time we need to query an attribute, which can get expensive
especially on networked file systems, we try to cache them instead. This
works perfectly fine for every '.gitattributes' file that is found, but
we hit cache invalidation problems when we determine that an attribuse
file is _not_ existing. We do create an entry in the cache for missing
'.gitattributes' files, but as soon as we hit that file again we
invalidate it and stat it again to see if it has now appeared.
In the case of diffing large trees with each other, this behaviour is
very suboptimal. For each pair of files that is to be diffed, we will
repeatedly query every directory component leading towards their
respective location for an attributes file. This leads to thousands or
even hundreds of thousands of wasted syscalls.
The attributes cache already has a mechanism to help in that scenario in
form of the `git_attr_session`. As long as the same attributes session
is still active, we will not try to re-query the gitmodules files at all
but simply retain our currently cached results. To fix our problem, we
can create a session at the top-most level, which is the initialization
of the `git_diff` structure, and use it in order to look up the correct
diff driver. As the `git_diff` structure is used to generate patches for
multiple files at once, this neatly solves our problem by retaining the
session until patches for all files have been generated.
The fix has been tested with linux.git by calling
`git_diff_tree_to_tree` and `git_diff_to_buf` with v4.10^{tree} and
v4.14^{tree}.
| time | .gitattributes stats
without fix | 33.201s | 844614
with fix | 30.327s | 4441
While execution only improved by roughly 10%, the stat(3) syscalls for
.gitattributes files decreased by 99.5%. The benchmarks were quite
simple with best-of-three timings on Linux ext4 systems. One can assume
that for network based file systems the performance gain will be a lot
larger due to a much higher latency.

streams: openssl: fix thread-safety for OpenSSL error messages
The function `ERR_error_string` can be invoked without providing a
buffer, in which case OpenSSL will simply return a string printed into a
static buffer. Obviously and as documented in ERR_error_string(3), this
is not thread-safe at all. As libgit2 is a library, though, it is easily
possible that other threads may be using OpenSSL at the same time, which
might lead to clobbered error strings.
Fix the issue by instead using a stack-allocated buffer. According to
the documentation, the caller has to provide a buffer of at least 256
bytes of size. While we do so, make sure that the buffer will never get
overflown by switching to `ERR_error_string_n` to specify the buffer's
size.

Fix unpack double free
If an element has been cached, but then the call to
packfile_unpack_compressed() fails, the very next thing that happens is
that its data is freed and then the element is not removed from the
cache, which frees the data again.
This change sets obj->data to NULL to avoid the double-free. It also
stops trying to resolve deltas after two continuous failed rounds of
resolution, and adds a test for this.

diff_file: properly refcount blobs when initializing file contents
When initializing a `git_diff_file_content` from a source whose data is
derived from a blob, we simply assign the blob's pointer to the
resulting struct without incrementing its refcount. Thus, the structure
can only be used as long as the blob is kept alive by the caller.
Fix the issue by using `git_blob_dup` instead of a direct assignment.
This function will increment the refcount of the blob without allocating
new memory, so it does exactly what we want. As
`git_diff_file_content__unload` already frees the blob when
`GIT_DIFF_FLAG__FREE_BLOB` is set, we don't need to add new code
handling the free but only have to set that flag correctly.

openssl: fix thread-safety on non-glibc POSIX systems
While the OpenSSL library provides all means to work safely in a
multi-threaded application, we fail to do so correctly. Quoting from
crypto_lock(3):
OpenSSL can safely be used in multi-threaded applications provided
that at least two callback functions are set, locking_function and
threadid_func.
We do in fact provide the means to set up the locking function via
`git_openssl_set_locking()`, where we initialize a set of locks by using
the POSIX threads API and set the correct callback function to lock and
unlock them.
But what we do not do is setting the `threadid_func` callback. This
function is being used to correctly locate thread-local data of the
OpenSSL library and should thus return per-thread identifiers. Digging
deeper into OpenSSL's documentation, the library does provide a fallback
in case that locking function is not provided by the user. On Windows
and BeOS we should be safe, as it simply "uses the system's default
thread identifying API". On other platforms though OpenSSL will fall
back to using the address of `errno`, assuming it is thread-local.
While this assumption holds true for glibc-based systems, POSIX in fact
does not specify whether it is thread-local or not. Quoting from
errno(3p):
It is unspecified whether errno is a macro or an identifier declared
with external linkage.
And in fact, with musl there is at least one libc implementation which
simply declares `errno` as a simple `int` without being thread-local. On
those systems, the fallback threadid function of OpenSSL will not be
thread-safe.
Fix this by setting up our own callback for this setting. As users of
libgit2 may want to set it themselves, we obviously cannot always set
that function on initialization. But as we already set up primitives for
threading in `git_openssl_set_locking()`, this function becomes the
obvious choice where to implement the additional setup.

diff_generate: fix unsetting diff flags
The macro `DIFF_FLAG_SET` can be used to set or unset a flag by
modifying the diff's bitmask. While the case of setting the flag is
handled correctly, the case of unsetting the flag was not. Instead of
inverting the flags, we are inverting the value which is used to decide
whether we want to set or unset the bits.
The value being used here is a simple `bool` which is `false`. As that
is being uplifted to `int` when getting the bitwise-complement, we will
end up retaining all bits inside of the bitmask. As that's only ever
used to set `GIT_DIFF_IGNORE_CASE`, we were actually always ignoring
case for generated diffs.
Fix that by instead getting the bitwise-complement of `FLAG`, not `VAL`.

diff: remove unused macros `DIFF_FLAG_*`
In commit 9be638ecf (git_diff_generated: abstract generated diffs,
2016-04-19), the code for generated diffs was moved out of the generic
"diff.c" and instead into its own module. During that conversion, it was
forgotten to remove the macros `DIFF_FLAG_IS_SET`, `DIFF_FLAG_ISNT_SET`
and `DIFF_FLAG_SET`, which are now only used in "diff_generated.c".
Remove those macros now.

refcount: make refcounting conform to aliasing rules
Strict aliasing rules dictate that for most data types, you are not
allowed to cast them to another data type and then access the casted
pointers. While this works just fine for most compilers, technically we
end up in undefined behaviour when we hurt that rule.
Our current refcounting code makes heavy use of casting and thus
violates that rule. While we didn't have any problems with that code,
Travis started spitting out a lot of warnings due to a change in their
toolchain. In the refcounting case, the code is also easy to fix:
as all refcounting-statements are actually macros, we can just access
the `rc` field directly instead of casting.
There are two outliers in our code where that doesn't work. Both the
`git_diff` and `git_patch` structures have specializations for generated
and parsed diffs/patches, which directly inherit from them. Because of
that, the refcounting code is only part of the base structure and not of
the children themselves. We can help that by instead passing their base
into `GIT_REFCOUNT_INC`, though.

signature: distinguish +0000 and -0000 UTC offsets
Git considers '-0000' a valid offset for signature lines. They need to
be treated as _not_ equal to a '+0000' signature offset. Parsing a
signature line stores the offset in a signed integer which does not
distinguish between `+0` and `-0`.
This patch adds an additional flag `sign` to the `git_time` in the
`signature` object which is populated with the sign of the offset. In
addition to exposing this information to the user, this information is
also used to compare signatures.

patch_parse: allow parsing ambiguous patch headers
The git patch format allows for having unquoted paths with whitespaces
inside. This format becomes ambiguous to parse, e.g. in the following
example:
diff --git a/file b/with spaces.txt b/file b/with spaces.txt
While we cannot parse this in a correct way, we can instead use the
"---" and "+++" lines to retrieve the file names, as the path is not
followed by anything here but spans the complete remaining line. Because
of this, we can simply bail outwhen parsing the "diff --git" header here
without an actual error and then proceed to just take the paths from the
other headers.

patch_parse: treat complete line after "---"/"+++" as path
When parsing the "---" and "+++" line, we stop after the first
whitespace inside of the filename. But as files containing whitespaces
do not need to be quoted, we should instead use the complete line here.
This fixes parsing patches with unquoted paths with whitespaces.

cmake: let USE_ICONV be optional on macOS
Instead of forcing iconv support on macOS (by forcing `USE_ICONV`
on), honor the `USE_ICONV` option only on macOS.
Although macOS includes iconv by default, some macOS users may have a
deficient installation for some reason and they should be provided a
workaround to use libgit2 even in this situation.
iconv support is now disabled entirely on non-macOS platforms. No other
platform supports core.precomposeunicode, and iconv should never be
linked.

config_parse: use common parser interface
As the config parser is now cleanly separated from the config file code,
we can easily refactor the code and make use of the common parser
module. This removes quite a lot of duplicated functionality previously
used for handling the actual parser state and replaces it with the
generic interface provided by the parser context.

config_file: split out module to parse config files
The configuration file code grew quite big and intermingles both actual
configuration logic as well as the parsing logic of the configuration
syntax. This makes it hard to refactor the parsing logic on its own and
convert it to make use of our new parsing context module.
Refactor the code and split it up into two parts. The config file code
will only handle actual handling of configuration files, includes and
writing new files. The newly created config parser module is then only
responsible for parsing the actual contents of a configuration file,
leaving everything else to callbacks provided to its provided function
`git_config_parse`.

parse: implement `git_parse_peek`
Some code parts need to inspect the next few bytes without actually
consuming it yet, for example to examine what content it has to expect
next. Create a new function `git_parse_peek` which returns the next byte
without modifying the parsing context and use it at multiple call sites.

patch_parse: use git_parse_contains_s
Instead of manually checking the parsing context's remaining length and
comparing the leading bytes with a specific string, we can simply re-use
the function `git_parse_ctx_contains_s`. Do so to avoid code duplication
and to further decouple patch parsing from the parsing context's struct
members.

parse: extract parse module
The `git_patch_parse_ctx` encapsulates both parser state as well as
options specific to patch parsing. To advance this state and keep it
consistent, we provide a few functions which handle advancing the
current position and accessing bytes of the patch contents. In fact,
these functions are quite generic and not related to patch-parsing by
themselves. Seeing that we have similar logic inside of other modules,
it becomes quite enticing to extract this functionality into its own
parser module.
To do so, we create a new module `parse` with a central struct called
`git_parse_ctx`. It encapsulates both the content that is to be parsed
as well as its lengths and the current position. `git_patch_parse_ctx`
now only contains this `parse_ctx` only, which is then accessed whenever
we need to touch the current parser. This is the first step towards
re-using this functionality across other modules which require parsing
functionality and remove code-duplication.

cmake: Allow user to select bundled zlib
Under some circumstances the installed / system version of zlib may not
be desirable due to being too old or buggy. This patch adds the option
`USE_BUNDLED_ZLIB` that will cause the bundled version of zlib to be
used.
We may also want to add similar functionality to allow the user to
select other bundled 3rd-party dependencies instead of using the system
versions.
