cairo: Introduce the concept of reference ownership

Also:
  * improving naming consistency
  * obsolete old/broken stuff
  * clean up tabs/space mix

NOTE: this removes the wrapper caches for Pattern and Surface as
there was no reliable way to clear them.

This is a merge from changes in Mono.Cairo in mono 3.2.
