t/variables.test fails on embedded server. Moved out that part again, to
a new test called t/variables-notembedded.test.


mysql-test/t/variables-notembedded.test:
  BitKeeper file /home/sven/bk/debug-max/5.1-new-rpl/mysql-test/t/variables-notembedded.test
mysql-test/r/variables-notembedded.result:
  Add -master.opt file to have a list of variables for slave_skip_errors.
mysql-test/r/variables.result:
  Variable variables not available in embedded mode to a new test,
  variables-notembedded.test
mysql-test/t/variables-notembedded-master.opt:
  Add --loose before --slave-skip-errors, so that it works if mtr is run
  with --embedded
mysql-test/t/variables.test:
  Variable variables not available in embedded mode to a new test,
  variables-notembedded.test. Result file updated accordingly.
