push over http: server side authorization support.

new hgrc entries allow_push, deny_push, push_ssl control push over http.

allow_push list controls push.  if empty or not set, no user can push.
if "*", any user (incl. unauthenticated user) can push.  if list of user
names, only authenticated users in list can push.

deny_push list examined before allow_push.  if "*", no user can push.
if list of user names, no unauthenticated user can push, and no users
in list can push.

push_ssl requires https connection for push.  default is true, so password
sniffing can not be done.
