  Move odb_backend implementors stuff into git2/sys This moves some of the odb_backend stuff that is related to the internals of an odb_backend implementation into include/git2/sys. Some of the stuff related to streaming I left in include/git2 because it seemed like it would be reasonably needed by a normal user who wanted to stream objects into and out of the ODB. Also, I added APIs for traversing the list of backends so that some of the tests would not need to access ODB internals.
