Prepare larger packet buffer for upload-pack protocol.
The original side-band support added to the upload-pack protocol used the default 1000-byte packet length. The pkt-line format allows up to 64k, so prepare the receiver for the maximum size, and have the uploader and downloader negotiate if larger packet length is allowed. Signed-off-by: Junio C Hamano <junkio@cox.net>
