MSYS/MinGW uses winsock but obviously doesn't set _MSC_VER. Use _WIN32
to decide whether to use winsock or BSD headers. Also remove these
headers from src/transport_git.c altogether, as they are not needed.

MSYS is very conservative, so we have to tell it that we don't care
about versions of Windows lower than WindowsXP. We also need to tell
CMake to add ws2_32 to the libraries list and we shouldn't add the
-fPIC option, to MSYS because it complains that it does it anyway.

Run `make -f Makefile.embed` to get a `libgit2.a` with no dependencies
and no configuration on any Unix-like system.

The generated library can be linked with any piece of software without
licensing issues.

Have fun.

repository: fix typo'ed assert

Restore config10 test file

Removing a section variable doesn't remove its section
header. Overwrite the config10 file so there are no changes after the
test is run.

Include common.h in hashtable.h

Without this, hashtable.h doesn't know what uint32_t is and the
compiler thinks that it's a function type.

If the section header is the last line in the file,
parse_section_header would incorrectly decide that the input had been
truncated.

Fix this by checking whether the actual input line is correctly
formatted.

Add extra braces to avoid ambiguous if-else.

Also, free() doesn't need a check.

Final fix for issue #278

git_signature__parse used to be very strict about what's a well-formed
signature. Add tests checking git_signature__parse can stick with
"unexpected" signatures (IOW no author name and / or no email, etc).

git_signature__parse used to be very strict about what's a well-formed
signature. Since git_signature__parse is used only when reading already
existing signatures, we should not care about if it's a valid signature
too much but rather show what we got.

The `stat` methods were having issues when called with a trailing slash
in Windows platforms.

We now use GetFileAttributes() where possible, which doesn't have this
restriction.

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.

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.
