Re: CAREFUL! No more delta object support!

Done.

					 I'm not sure I
want to write the "parse incoming pack-file" thing, but git-unpack-objects
comes _reasonably_ close (but right now it seeks around using the index
file to resolve deltas, instead of keeping them in memory and resolving
them when possible).

I'm still thinking about this one. I think I'll just do it.

One problem here is that since we don't know how big the incoming
pack-file will be, in a streaming input environment the receiver needs to
either make the pack-file reception be the last thing it sees, or it will
have to live with the fact that "git-unpack-objects" will read some more
than it needs before it notices that it got it all...

We can handle the latter either by padding (make the rule be that
git-unpack-file will always read in chunks of 4kB max, and pad the output
with 4kB of zero bytes or something, and then you can execute
git-unpack-objects and continue reading stdin afterwards, removing any
zeroes that git-unpack-file didn't eat), or by having git-unpack-objects 
flush anything after the final SHA1 to _its_ stdout, so that you can get 
the following data/commands in the stream from the unpack-file thing. 
Ugly, in any case.
