largefiles: batch statlfile requests when pushing a largefiles repo (issue3386)
This implements a part of issue 3386. It batches the request for the status of
all largefiles in the revisions that are about to be pushed into a single
request, instead of doing N separate requests.
In a real world test case, this change was verified to save 1,116 round-trips to
the server. It only requires a client-side change; it is backwards-compatible
with an older version of the server.
