Subclass TextViewer to add mock methods instead of monkey-patching it.

Patch by Steve Dougherty.

- Nix the 'noxp' option, it was for Win2k compatibility (which was dropped
  with Python 3.3) and made default ttk ugly on post-Win2k systems (#21665)
- Use 'OPTS=symbols' instead of 'DEBUG=1'; symbols is the official method
- Use core, shell, dlls, install-binaries, and install-libraries targets
  instead of all and install to avoid trying to 1) build packages that don't
  work with MSVC 10+ and 2) install unnecessary bits and pieces.

Before, regrtest failed to remove the temporary test directory because the
process was still running in this directory.
