alloc: don't overwrite allocator during init if set
If the allocator has been set before we the library is initialised, we would
replace that setting with the standard allocator contrary to the user's wishes.

mbedtls: fix `inline` being used in mbedtls headers
The mbedtls headers make direct use of the `inline` attribute to
instruct the compiler to inline functions. As this function is not C90
compliant, this can cause the compiler to error as soon as any of these
files is included and the `-std=c90` flag is being added.
The mbedtls headers declaring functions as inline always have a prelude
which define `inline` as a macro in case it is not yet defined. Thus, we
can easily replace their define with our own define, which simply copies
the logic of our own `GIT_INLINE` macro.

cmake: distinguish internal and system include directories
While we want to enforce strict C90 mode, this may cause issues with
system provided header files which are themselves not strictly
conforming. E.g. if a system header has C++ style comments, a compiler
in strict C90 mode would produce an error and abort the build. As the
user most likely doesn't want to change the system header, this would
completely break the build on such systems. One example of this is
mbedtls, which provides such header files.
The problem can be worked around by distinguishing between
system-provided and project-provided include directories. When adding
include directories via "-isystem" instead of "-I", the compiler will
skip certain checks and print out less warnings. To use system includes,
we can simply add the "SYSTEM" flag to CMake's `INCLUDE_DIRECTORIES` and
`TARGET_INCLUDE_DIRECTORIES` functions. Note that we have to split the
include directories into two variables because of this, as we definitely
still want to check for all warnings produced by our own header files.

cmake: enforce C90 standard
While the aim of libgit2 was to conform to C90 code, we never instructed
the compiler to enforce C90 compliance. Thus, quite a few violations
were able to get into our code base, which have been removed with the
previous commits. As we are now able to build libgit2 with C90 enforced,
we can set the C_STANDARD property for our own build targets.
Note that we explicitly avoid setting the C standard for our third-party
dependencies. At least the zlib target does not build with C90 enforced,
and we do not want to fix them by deviating from upstream. Thus we
simply enforce no standard for them.

treewide: remove use of C++ style comments
C++ style comment ("//") are not specified by the ISO C90 standard and
thus do not conform to it. While libgit2 aims to conform to C90, we did
not enforce it until now, which is why quite a lot of these
non-conforming comments have snuck into our codebase. Do a tree-wide
conversion of all C++ style comments to the supported C style comments
to allow us enforcing strict C90 compliance in a later commit.

treewide: avoid use of `inline` attribute
ISO C90 does not specify the `inline` attribute, and as such we cannot
use it in our code. While we already use `__inline` when building in
Microsoft Visual Studio, we should also be using the `__inline__`
attribute from GCC/Clang. Otherwise, if we're using neither MSVC nor
GCC/Clang, we should simply avoid using `inline` at all and just define
functions as static.
This commit adjusts our own `GIT_INLINE` macro as well as the inline
macros specified by khash and xdiff. This allows us to enable strict C90
mode in a later commit.

streams: report OpenSSL errors if global init fails
In case when the global initialization of the OpenSSL stream fails, the
user is left without any hint as to what went wrong as we do not provide
any error message at all. This commit refactors the init function to
have a common error path, which now also sets an error message including
the error string provided by OpenSSL.

delta: fix overflow when computing limit
When checking whether a delta base offset and length fit into the base
we have in memory already, we can trigger an overflow which breaks the
check. This would subsequently result in us reading memory from out of
bounds of the base.
The issue is easily fixed by checking for overflow when adding `off` and
`len`, thus guaranteeting that we are never indexing beyond `base_len`.
This corresponds to the git patch 8960844a7 (check patch_delta bounds
more carefully, 2006-04-07), which adds these overflow checks.

settings: optional unsaved index safety
Add the `GIT_OPT_ENABLE_UNSAVED_INDEX_SAFETY` option, which will cause
commands that reload the on-disk index to fail if the current
`git_index` has changed that have not been saved. This will prevent
users from - for example - adding a file to the index then calling a
function like `git_checkout` and having that file be silently removed
from the index since it was re-read from disk.
Now calls that would re-read the index will fail if the index is
"dirty", meaning changes have been made to it but have not been written.
Users can either `git_index_read` to discard those changes explicitly,
or `git_index_write` to write them.

(when the on-disk index has not changed) does _not_ reset the dirty
flag as we have not updated the contents of our index and our unsaved

index: add a dirty bit reflecting unsaved changes
Teach the index when it is "dirty", and has unsaved changes. Consider
the index dirty whenever a caller has added or removed an entry from the
main index, REUC or NAME section, including when the index is completely
cleared. Similarly, consider the index _not_ dirty immediately after it
is written, or when it is read from the on-disk index.
This allows us to ensure that unsaved changes are not lost when we
automatically refresh the index.

Since commit 630a67366 (refspec: add public parsing api, 2018-02-07), we
now have two functions `git_refspec_free` and `git_refspec__free`. The
difference is that the first one will free the structure itself, while
the second one will only free the structure's contents. Use our new
`dispose` naming pattern for the latter function to help avoid
confusion.

delta: fix out-of-bounds read of delta
When computing the offset and length of the delta base, we repeatedly
increment the `delta` pointer without checking whether we have advanced
past its end already, which can thus result in an out-of-bounds read.
Fix this by repeatedly checking whether we have reached the end. Add a
test which would cause Valgrind to produce an error.

delta: fix sign-extension of big left-shift
Our delta code was originally adapted from JGit, which itself adapted it
from git itself. Due to this heritage, we inherited a bug from git.git
in how we compute the delta offset, which was fixed upstream in
48fb7deb5 (Fix big left-shifts of unsigned char, 2009-06-17). As
explained by Linus:
Shifting 'unsigned char' or 'unsigned short' left can result in sign
extension errors, since the C integer promotion rules means that the
unsigned char/short will get implicitly promoted to a signed 'int' due to
the shift (or due to other operations).
This normally doesn't matter, but if you shift things up sufficiently, it
will now set the sign bit in 'int', and a subsequent cast to a bigger type
(eg 'long' or 'unsigned long') will now sign-extend the value despite the
original expression being unsigned.
One example of this would be something like
unsigned long size;
unsigned char c;
size += c << 24;
where despite all the variables being unsigned, 'c << 24' ends up being a
signed entity, and will get sign-extended when then doing the addition in
an 'unsigned long' type.
Since git uses 'unsigned char' pointers extensively, we actually have this
bug in a couple of places.
In our delta code, we inherited such a bogus shift when computing the
offset at which the delta base is to be found. Due to the sign extension
we can end up with an offset where all the bits are set. This can allow
an arbitrary memory read, as the addition in `base_len < off + len` can
now overflow if `off` has all its bits set.
Fix the issue by casting the result of `*delta++ << 24UL` to an unsigned
integer again. Add a test with a crafted delta that would actually
succeed with an out-of-bounds read in case where the cast wouldn't
exist.

deps: fix implicit fallthrough warning in http-parser
GCC 7 has introduced new warnings for implicit fallthrough in switch
statements. Whenever there is no branch in a case block, GCC will watch
out for some heuristics which indicate that the implicit fallthrough is
intended, like a "fallthrough" comment. The third-party http-parser code
manages to trick this heuristic in one case, even though there is a
"FALLTHROUGH" comment. Fortunately, GCC has also added a strictness
level to the -Wimplicit-fallthrough diagnostic, such that we can loosen
this heuristic and make it more lax.
Set -Wimplicit-fallthrough=1 in http-parser's CMake build instructions,
which is the strictest level that gets rid of the warning. This level
will treat any kind of comment as a "fallthrough" comment, which
silences the warning.

config_parse: have `git_config_parse` own entry value and name
The function `git_config_parse` uses several callbacks to pass data
along to the caller as it parses the file. One design shortcoming here
is that strings passed to those callbacks are expected to be freed by
them, which is really confusing.
Fix the issue by changing memory ownership here. Instead of expecting
the `on_variable` callbacks to free memory for `git_config_parse`, just
do it inside of `git_config_parse`. While this obviously requires a bit
more memory allocation churn due to having to copy both name and value
at some places, this shouldn't be too much of a burden.
