Hi,

Here are a few patches that GitHub has been running to get rid of the
rename-to-old behavior that 'git repack' has when its invocation of
'pack-objects' produced a pack that already exists.

This was developed in the context of a circular dependency involving
writing a multi-pack index during 'git repack' (we have some patches
that do so by adding a '--write-midx' in the repack builtin), but it
should be generally useful.

The idea (which is explained in detail in the final patch) is that prior
to 1190a1acf8 (pack-objects: name pack files after trailer hash,
2013-12-05), 'git repack' had to move existing packs out of the way for
safety, but after 1190a1acf8 no longer needs to do so.

This makes 'git repack' a little simpler since it no longer has to deal
with any failures encountered during this rename-to-old behavior. It
also paves the way for sending the MIDX-during-repack patches.

Thanks,
Taylor
