Fix compilation error in MSVC when compiling for c++

Do not mess with environment variables anymore. The new external API has
more helper methods, and everything is explicit.

If a config has several files, we need to check all of them before we
can say that a variable doesn't exist.

The repo's configuration should take precedence over the global one.

It's not enough to load the config, we also need to explicitely parse
it after we create it.

This function puts the global and repository configurations in one
git_config object and gives it to the user.

Runtime checks are asserting on the embedded ZLib code because of
truncation (see zlib/trees.c:218). This is not good or pretty, but I'm
wary about patching the ZLib code even more.

There are two ways to fix this:

	- Patch the ZLib code, and start storing a diff/patchset on
	how does our version of ZLib differ from the original one, so we can
	be more or less on sync when new version of ZLib.

	- Go back to ZLib as an external dependency, which is np for *NIX
	users but annoying as dicks for Windows users.

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.
