Simplify loose ref writing

There is no need to store the format outselves, as the library
provides git_filebuf_printf which takes care of the formatting itself.

Also get rid of an use of strcat + strcpy which is always a nice
thing.

Fix all the missmatched arguments in the docs

Drop redundant methods. The ncmp method is now public

Yeah. Finally. Fuck the old names, this ain't POSIX
and they don't make any sense at all.

Same name as `git_config_foreach`

Implement config writing

Fix: GIT_PATH_PATH_SEPARATOR is now a semi-colon under Windows.

GIT_PATH_LIST_SEPARATOR and GIT_PATH_MAX are made public so
that it's can be used by a client.

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.
