  Issue #11286: Fixed unpickling of empty 2.x strings.
........

Many tests simply didn't care if they unset a pre-existing trace function. This
made test coverage impossible. This patch fixes various tests to put back any
pre-existing trace function. It also introduces test.support.no_tracing as a
decorator which will temporarily unset the trace function for tests which
simply fail otherwise.

Thanks to Kristian Vlaardingerbroek for helping to find the cause of various
trace function unsets.

  Issue 7128: Removed reference to the non-existent copyreg module.

  The reference to copyreg was a unnoticed leftover from the compatibility
  support for the grand renaming of the standard library in Python 3. The
  compatibility support was reverted in r63493, but not completely as this
  patch shows.

  Based on a patch by Amaury Forgeot d'Arc.
