When creating branch c/d check that branch c does not already exists.
With packed refs, there may not be a ".git/refs/heads/c" file
when branch c exists. And currently in this case, there is no check
to prevent creation of branch c/d.
This should probably be rewritten in C and done after the ref lock
has been taken to make sure no race exists though.

This eliminates many struct pack_entry usages since this structure
