ENH: Teach CTest to handle Bazaar repositories

This creates cmCTestBZR to drive CTest Update handling on bzr-based work
trees.  Currently we always update to the head of the remote tracking
branch (bzr pull), so the nightly start time is ignored for Nightly
builds.  A later change will address this.  Patch from Tom Vercauteren.
See issue #6857.
