fetch: support fetching from a shallow repository
This patch just put together pieces from the 8 steps patch. We stop at
step 7 and reject refs that require new shallow commits.
Note that, by rejecting refs that require new shallow commits, we
leave dangling objects in the repo, which become "object islands" by
the next "git fetch" of the same source.
If the first fetch our "ours" set is zero and we do practically
nothing at step 7, "ours" is full at the next fetch and we may need to
walk through commits for reachability test. Room for improvement.
