unix: posix: avoid use of variadic macro `p_snprintf`
The macro `p_snprintf` is implemented as a variadic macro that
calls `snprintf` directly with `__VA_ARGS__`. In C89, variadic
macros are not allowed, but as the arguments of `p_snprintf` and
`snprintf` are matching 1:1, we can fix this by simply removing
the parameter list from `p_snprintf`.

regexec: prefix all regexec function calls with p_
Prefix all the calls to the the regexec family of functions with `p_`.
This allows us to swap out all the regular expression functions with our
own implementation. Move the declarations to `posix_regex.h` for
simpler inclusion.

features.h: allow building without CMake-generated feature header
In commit a390a8464 (cmake: move defines into "features.h" header,
2017-07-01), we have introduced a new "features.h" header. This file is
being generated by the CMake build system based on how the libgit2 build
has been configured, replacing the preexisting method of simply setting
the defines inside of the CMake build system. This was done to help
splitting up the build instructions into multiple separate
subdirectories.
An overlooked shortcoming of this approach is that some projects making
use of libgit2 build the library with custom build systems, without
making use of CMake. For those users, the introduction of the
"features.h" file makes their life harder as they would have to also
generate this file.
Fix this issue by guarding all inclusions of the generated header file
by the `LIBGIT2_NO_FEATURES_H` define. Like this, other build systems
can skip the feature header and simply define all used features by
specifying `-D` flags for the compiler again.

cmake: move regcomp and futimens checks to "features.h"
In our CMakeLists.txt, we have to check multiple functions in order to
determine if we have to use our own or whether we can use the
platform-provided one. For two of these functions, namely `regcomp_l()`
and `futimens`, the defined macro is actually used inside of the header
file "src/unix/posix.h". As such, these macros are not only required by
the library, but also by our test suite, which is makes use of internal
headers.
To prepare for the CMakeLists.txt split, move these two defines inside
of the "features.h" header.

cmake: move defines into "features.h" header
In a future commit, we will split out the build instructions for our
library directory and move them into a subdirectory. One of the benefits
is fixing scoping issues, where e.g. defines do not leak to build
targets where they do not belong to. But unfortunately, this does also
pose the problem of how to propagate some defines which are required by
both the library and the test suite.
One way would be to create another variable keeping track of all added
defines and declare it inside of the parent scope. While this is the
most obvious and simplest way of going ahead, it is kind of unfortunate.
The main reason to not use this is that these defines become implicit
dependencies between the build targets. By simply observing a define
inside of the CMakeLists.txt file, one cannot reason whether this define
is only required by the current target or whether it is required by
different targets, as well.
Another approach would be to use an internal header file keeping track
of all defines shared between targets. While configuring the library, we
will set various variables and let CMake configure the file, adding or
removing defines based on what has been configured. Like this, one can
easily keep track of the current environment by simply inspecting the
header file. Furthermore, these dependencies are becoming clear inside
the CMakeLists.txt, as instead of simply adding a define, we now call
e.g. `SET(GIT_THREADSAFE 1)`.
Having this header file though requires us to make sure it is always
included before any "#ifdef"-preprocessor checks are executed. As we
have already refactored code to always include the "common.h" header
file before any statement inside of a file, this becomes easy: just make
sure "common.h" includes the new "features.h" header file first.

Make sure to always include "common.h" first
Next to including several files, our "common.h" header also declares
various macros which are then used throughout the project. As such, we
have to make sure to always include this file first in all
implementation files. Otherwise, we might encounter problems or even
silent behavioural differences due to macros or defines not being
defined as they should be. So in fact, our header and implementation
files should make sure to always include "common.h" first.
This commit does so by establishing a common include pattern. Header
files inside of "src" will now always include "common.h" as its first
other file, separated by a newline from all the other includes to make
it stand out as special. There are two cases for the implementation
files. If they do have a matching header file, they will always include
this one first, leading to "common.h" being transitively included as
first file. If they do not have a matching header file, they instead
include "common.h" as first file themselves.
This fixes the outlined problems and will become our standard practice
for header and source files inside of the "src/" from now on.

p_snprintf: no need for arguments to a format
`snprintf` requires a _format_ but does not require _arguments_ to the
format. eg: `snprintf(buf, 42, "hi")` is perfectly legal. Expand the
macro to match.
Without this, `p_sprintf(buf, 42, "hi")` errors with:
```
error: expected expression
p_snprintf(msg, 42, "hi");
^
src/unix/posix.h:53:34: note: expanded from macro 'p_snprintf'

threads: introduce `git_thread_exit`
Introduce `git_thread_exit`, which will allow threads to terminate at an
arbitrary time, returning a `void *`. On Windows, this means that we
need to store the current `git_thread` in TLS, so that we can set its
`return` value when terminating.
We cannot simply use `ExitThread`, since Win32 returns `DWORD`s from
threads; we return `void *`.

the `st_mtim` / `st_mtimespec` definition on other systems (much like
the existing `st_mtime` backcompat definition).

crlf: tick the index forward to work around racy-git behaviour
In order to avoid racy-git, we zero out the file size for entries with
the same timestamp as the index (or during the initial checkout). This
is the case in a couple of crlf tests, as the code is fast enough to do
everything in the same second.
As we know that we do not perform the modification just after writing
out the index, which is what this is designed to work around, tick the
mtime of the index file such that it doesn't agree with the files
anymore, and we do not zero out these entries.

Test cancel from indexer progress callback
This adds tests that try canceling an indexer operation from

After writing the tests, I wanted to run this under valgrind and
had a number of errors in that situation because mmap wasn't
working. I added a CMake option to force emulation of mmap and
consolidated the Amiga-specific code into that new place (so we
don't actually need separate Amiga code now, just have to turn on
-DNO_MMAP).
Additionally, I made the indexer code propagate error codes more
reliably than it used to.

Make tree iterator handle icase equivalence
There is a serious bug in the previous tree iterator implementation.
If case insensitivity resulted in member elements being equivalent
to one another, and those member elements were trees, then the
children of the colliding elements would be processed in sequence
instead of in a single flattened list. This meant that the tree
iterator was not truly acting like a case-insensitive list.
This completely reworks the tree iterator to manage lists with
case insensitive equivalence classes and advance through the items
in a unified manner in a single sorted frame.
It is possible that at a future date we might want to update this
to separate the case insensitive and case sensitive tree iterators
so that the case sensitive one could be a minimal amount of code
and the insensitive one would always know what it needed to do
without checking flags.
But there would be so much shared code between the two, that I'm
not sure it that's a win. For now, this gets what we need.
More tests are needed, though.

Add template dir and set gid to repo init
This extends git_repository_init_ext further with support for

Also, this adds a bunch of new utility functions including a
very general purpose `git_futils_mkdir` (with the ability to
make paths and to chmod the paths post-creation) and a file
tree copying function `git_futils_cp_r`. Also, this includes
some new path functions that were useful to keep the code
simple.

Migrate ODB files to new error handling
This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to
the new style of error handling. Also got the unix and win32
versions of map.c. There are some minor changes to other
files but no others were completely converted.
This also contains an update to filebuf so that a zeroed out
filebuf will not think that the fd (== 0) is actually open
(and inadvertently call close() on fd 0 if cleaned up).
Lastly, this was built and tested on win32 and contains a
bunch of fixes for the win32 build which was pretty broken.

Update diff to use iterators
This is a major reorganization of the diff code. This changes
the diff functions to use the iterators for traversing the

this moved the functions relating to outputting a diff into a
new file (diff_output.c).
This includes a number of other changes - adding utility
functions, extending iterators, etc. plus more tests for the
diff code. This also takes the example diff.c program much
further in terms of emulating git-diff command line options.

posix: Portable `vsnprintf`
Our good, lovely folks at Microsoft decided that there was no good
reason to make `vsnprintf` compilant with the C standard, so that
function in Windows returns -1 on overflow, instead of returning the
actual byte count needed to write the full string.
We now handle this situation more gracefully with the POSIX
compatibility layer, by returning the needed byte size using an
auxiliary method instead of blindly resizing the target buffer until it
fits.
This means we can now support `printf`s of any size by allocating a
temporary buffer. That's good.

fileops: Drop `git_fileops_prettify_path`
The old `git_fileops_prettify_path` has been replaced with
`git_path_prettify`. This is a much simpler method that uses the OS's
`realpath` call to obtain the full path for directories and resolve
symlinks.
The `realpath` syscall is the original POSIX call in Unix system and
an emulated version under Windows using the Windows API.

fileops: Cleanup
Cleaned up the structure of the whole OS-abstraction layer.
fileops.c now contains a set of utility methods for file management used
by the library. These are abstractions on top of the original POSIX
calls.
There's a new file called `posix.c` that contains
emulations/reimplementations of all the POSIX calls the library uses.
These are prefixed with `p_`. There's a specific posix file for each
platform (win32 and unix).
All the path-related methods have been moved from `utils.c` to `path.c`
and have their own prefix.

Revised platform types to use 'best supported' size.
This will allow graceful migration to 64 bit file sizes and timestamps should
git's binary interface be extended to allow this.

Remove git_errno
It was not being used by any methods (only by malloc and calloc), and
since it needs to be TLS, it cannot be exported on DLLs on Windows.
Burn it with fire. The API always returns error codes!

win32: Add routines to abstract memory-mapped file functions
In particular, the git__mmap() and git__munmap() routines provide
the interface to platform specific memory-mapped file facilities.
We provide implementations for unix and win32, which can be found
in their own sub-directories.
