Fix directory/path manipulation methods

2011-02-05T10:42:41+00:00

The `dirname` and `dirbase` methods have been replaced with the Android
implementation, which is actually compilant to some kind of standard.

A new method `topdir` has been added, which returns the topmost
directory in a path.

These changes fix issue #49:

	`gitfo_prettify_dir_path` converts "./.git/" to ".git/", so
	the code at src/repository.c:190 goes out of bounds when
	trying to find the topmost directory.

	The new `git__topdir` method handles this gracefully, and the
	fixed `git__dirname` now returns the proper value for the
	repository's working dir.

	E.g.

		/repo/.git/ ==> working dir '/repo/'
		.git/		==> working dir '.'

Add generic hash function to util.c

2010-12-29T22:31:58+00:00

It's MurmurHash3 slightly edited to make it
cross-platform. Fast and neat.

Use this for hashing strings on hash tables instead
of a full SHA1 hash. It's very fast and well distributed.

Obviously not crypto-secure.

Remove git_errno

2010-12-22T22:15:09+00:00

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!
