Once all new packs are known to exist, 'repack' installs their contents from their temporary location into their permanent one. This is a semi-involved procedure for each pack, since for each extension (e.g., ".idx", ".pack", ".mtimes", and so on) we have to either: - adjust the filemode of the temporary file before renaming it into place, or - die() if we are missing a non-optional extension, or - unlink() any existing file for extensions that we did not generate (e.g., if a non-cruft pack we generated was identical to, say, a cruft pack which existed at the beginning of the process, we have to remove the ".mtimes" file). Extract this procedure into its own function, and call it "generated_pack_install"(). This will set us up for pulling this function out of the builtin entirely and making it part of the repack.h API, which will be done in a future commit.
