README.md: do not break syntax highlighting

Signed-off-by: schu <schu-github@schulog.org>

Port MSVC specific Waf compilation flags to CMake and remove dynamic dependence to msvcr100.dll on Windows

The '/MT' and '/MTd' flags replace the dynamic link to 'msvcr100.dll' with a static link to 'libcmt.lib'. This has the nice effect to ease the deployment of libgit2 by removing the dependence on 'msvcr100.dll' which is not deployed by default on Windows.

Goodbye Waf. It's been a long ride.

All the custom backend code will be moved to a separate project,
	together with the new MySQL backend.

Remove uneeded arpa/inet.h include

This header isn't needed at all and it shows a lot of warnings on
OpenBSD.

Msvc10 fixes

The better solution would probably be to turn the gitfo_lstat /
gitfo_readlink macros into real functions that wrap either lstat or
gitfo_lstat__w32 (and readlink or gitfo_readlink__w32). However, that
would introduce an indirection unless inlined. For now, this is the less
intrusive change.

MSVC supports "inline" only in C++ code, not in C code.

git_tag_create{,_o,_frombuffer} correction and improvement

Commit short message should be the same as git's

Handle Symlinks if they can be handled in Win32. This is not even
compiled. Needs review.

The lstat implementation is modified from core Git.
The readlink implementation is modified from PHP.

Keep the lockfile if we fail to lock it

In git, the short message of a commit is the part of the commit message before 2 consecutive line breaks. In the short message, line breaks are replaced by space characters.

Add a check for the file descriptor in git_filebuf_cleanup. Without
it, an existing lockfile would be deleted if we tried to acquire it
(but failed, as the lockfile already existed).
