https: warn when server certificate isn't verified

Mercurial will verify HTTPS server certificates if web.cacerts is configured,
but it will by default silently not verify any certificates.

We now warn the user that when the certificate isn't verified she won't get the
security she might expect from https:
  warning: localhost certificate not verified (check web.cacerts config setting)

Self-signed certificates can be accepted silently by configuring web.cacerts to
point to a suitable certificate file.

# simple script to be used in hooks
# copy it to the current directory when the test starts:
#
#     cp "$TESTDIR"/printenv.py .
#
# put something like this in the repo .hg/hgrc:
#
#     [hooks]
#     changegroup = python ../printenv.py <hookname> [exit] [output]
#
#   - <hookname> is a mandatory argument (e.g. "changegroup")
#   - [exit] is the exit code of the hook (default: 0)
#   - [output] is the name of the output file (default: use sys.stdout)
#              the file will be opened in append mode.
