The methods previously known as

	git_repository_lookup
	git_repository_newobject
	git_repository_lookup_ref

are now part of their respective namespaces:

	git_object_lookup
	git_object_new
	git_reference_lookup

This makes the API more consistent with the new references API.

Tests are now declared with detailed descriptions and a short test name:

	BEGIN_TEST(the_test0, "this is an example test that does something")
		...
	END_TEST

Modules are declared through a simple macro interface:

	BEGIN_MODULE(mod_name)
		ADD_TEST(the_test0);
		...
	END_MODULE

Error messages when tests fail have been greatly improved.

Add test deleteref::deleting_a_ref_which_is_both_packed_and_loose_should_remove_both_tracks_in_the_filesystem()

Renaming a packed reference should not pack another reference
which happens to be in both loose and pack state.

Forces a move by creating the folder for the destination file, if it
doesn't exist.

Test helper function which recursively copies the content of a
directory. This function has been tweaked to prevent stack overflows by
reusing the same path buffers on all recursive calls.

The following methods have been implemented:

	git_reference_packall
	git_reference_rename
	git_reference_delete

The library now has full support for packed references, including
partial and total writing. Internal documentation has been updated with
the details.

These two reference types are now stored separately to eventually allow
the removal/renaming of loose references and rewriting of the refs
packfile.
