fetch-pack: -k option to keep downloaded pack.
Split out the functions that deal with the socketpair after finishing git protocol handshake to receive the packed data into a separate file, and use it in fetch-pack to keep/explode the received pack data. We earlier had something like that on clone-pack side once, but the list discussion resulted in the decision that it makes sense to always keep the pack for clone-pack, so unpacking option is not enabled on the clone-pack side, but we later still could do so easily if we wanted to with this change.
