mysql-test-run.pl, mtr_cases.pl

  - Back porting of some changes in later releases
  - Corrected valgrind support
  - Removed work around for TZ needed in VisualStudio 6
  - Don't restart master to add special settings from "<testcase>-master.opt",
    if same settngs as running master, feature request in bug#12433
  - With --reorder, keep tests with same *-master.opt content together,
    to save even more master restarts


mysql-test/lib/mtr_misc.pl:
  Added functions to compare lists of options
mysql-test/lib/mtr_cases.pl:
  Removed special code for Windows as in VC6 we unset
  TZ to avoid library bug
mysql-test/mysql-test-run.pl:
  Handle pseudo option --timezone=<spec> that sets TZ
