ENH: Rewrite CTest Update implementation

This adds a new VCS update implementation to the cmCTestVC hierarchy and
removes it from cmCTestUpdateHandler.  The new implementation has the
following advantages:

  - Factorized implementation instead of monolithic function
  - Logs vcs tool output as it is parsed (less memory, inline messages)
  - Uses one global svn log instead of one log per file
  - Reports changes on cvs branches (instead of latest trunk change)
  - Generates simpler Update.xml (only one Directory element per dir)

Shared components of the new implementation appear in cmCTestVC and may
be re-used by subclasses for other VCS tools in the future.
