	* test.cs: make the sample program dump all the refs.

	* Lib/Repository.cs: Expose GetAllRefs.

	* Lib/RefDatabase.cs (ReadOneLooseRef): Do not crash if the
	refName is not present in the looseKeys.

	(RefreshPackedRefs): If the packed-refs file does not exist, do
	not try to continue, it would otherwise crash.
