http client: support persistent connections.

uses keepalive module from urlgrabber package.  tested against "hg serve",
cgi server, and through http proxy.  used ethereal to verify that only
one tcp connection used during entire "hg pull" sequence.

if server supports keepalive, this makes latency of "hg pull" much lower.
