Update http-push functionality
This brings http-push functionality more in line with the ssh/git version, by borrowing bits from send-pack and rev-list to process refspecs and revision history in more standard ways. Also, the status of remote objects is determined using PROPFIND requests for the object directory rather than HEAD requests for each object - while it may be less efficient for small numbers of objects, this approach is able to get the status of all remote loose objects in a maximum of 256 requests. Signed-off-by: Junio C Hamano <junkio@cox.net>
