So a quick fix to get the chk + gc stuff working is this diff:

Basically, it forces the generic fetching to work in terms of fulltexts,
and turns 'autopack' into a no-op. (It currently fails because GC
repositories hold different info in the index than other repos, and the
auto-pack code makes assumptions.)

- From what I can tell, if I don't set fetch_uses_deltas, there is
something about my repo which causes a delta to be transmitted before
its compression parent, which means that the GC repository cannot adapt
it into a fulltext for insertion. I assume it has something to do with
newer sort orderings for transmitting deltas, etc. (Remembering that
adapters running inside "insert_record_stream()" adapt based on what is
already present in the target repo, not based on requesting more data
from the source repository.)

There are certainly other/better fixes, but this at least gets things
*working* again, and we can move on from here.

Robert, do you want to have this patch, or wait until a more-correct fix
is written?
