sslutil: remove ui from sslkwargs (API)

Arguments to sslutil.wrapsocket() are partially determined by
calling sslutil.sslkwargs(). This function receives a ui and
a hostname and determines what settings, if any, need to be
applied when the socket is wrapped.

Both the ui and hostname are passed into wrapsocket(). The
other arguments to wrapsocket() provided by sslkwargs() (ca_certs
and cert_reqs) are not looked at or modified anywhere outside
of sslutil.py. So, sslkwargs() doesn't need to exist as a
separate public API called before wrapsocket().

This commit starts the process of removing external consumers of
sslkwargs() by removing the "ui" key/argument from its return.
All callers now pass the ui argument explicitly.

# Extract version number into 4 parts, some of which may be empty:
#
# version: the numeric part of the most recent tag. Will always look like 1.3.
#
# type: if an rc build, "rc", otherwise empty
#
# distance: the distance from the nearest tag, or empty if built from a tag
#
# node: the node|short hg was built from, or empty if built from a tag
