The struct `packed_git` holds information regarding a packed object file. Let's add the repository variable to this object, to represent the repository that this packfile belongs to. This helps remove dependency on the global `the_repository` object in `packfile.c` by simply using repository information now readily available in the struct.
We do need to consider that a pack file could be part of the alternates of a repository, but considering that we only have one repository struct and also that we currently anyways use 'the_repository'. We should be OK with this change.
We also modify `alloc_packed_git` to ensure that the repository is added to newly created `packed_git` structs. This requires modifying the function and all its callee to pass the repository object down the levels.
