Implement fetching from a packed repository over http/https using the dumb server support files. I consider some parts of the logic should be in a separate C program, but it appears to work with my simple tests. I have backburnered it for a bit too long for my liking, so let's throw it out in the open and see what happens. Signed-off-by: Junio C Hamano <junkio@cox.net>
