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.
