receive-pack: allow a maximum input size to be specified
Receive-pack feeds its input to either index-pack or
unpack-objects, which will happily accept as many bytes as
a sender is willing to provide. Let's allow an arbitrary
cutoff point where we will stop writing bytes to disk.
Cleaning up what has already been written to disk is a
related problem that is not addressed by this patch.
