git__delta_apply used to return with a generic GIT_ERROR when allocating
memory for the delta failed.

Fix this to return GIT_ENOMEM.

"git_config_backend" have been renamed to "git_config_file", which
implements a generic interface to access a configuration file -- be it
either on disk, from a DB or whatever mumbojumbo.

We have a lot of utility methods that make path building trivial. Use
them!

A couple of config improvements

cvar_normalize_name to reflect the incompatible change.
