libgit2/tests/t10-refs.c
Vicent Marti 87d3acf45e Finish the References API
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.
