repack: consider bitmaps when performing repacks
Since `pack-objects` will write a `.bitmap` file next to the `.pack` and `.idx` files, this commit teaches `git-repack` to consider the new bitmap indexes (if they exist) when performing repack operations. This implies moving old bitmap indexes out of the way if we are repacking a repository that already has them, and moving the newly generated bitmap indexes into the `objects/pack` directory, next to their corresponding packfiles. Since `git repack` is now capable of handling these `.bitmap` files, a normal `git gc` run on a repository that has `pack.writebitmaps` set to true in its config file will generate bitmap indexes as part of the garbage collection process. Alternatively, `git repack` can be called with the `-b` switch to explicitly generate bitmap indexes if you are experimenting and don't want them on all the time.
