Improve restart logic all code to detect restart is now in the functions

'run_testcase_need_master/slave_restart'
Remove the faulty qw
Only look for mysql_fix_privilege_tables if not windows


mysql-test/lib/mtr_cases.pl:
  Move all code to determine when to restart into 'run_testcase_need_master/slave_restart' 
  Add possibility to wite --force-restart in -master.opt file, this will force a restart and
  since master is not started with any special options there is no need to restart
  again afterwards.
mysql-test/mysql-test-run.pl:
  Remove the qw surrounding ENV{'LD_LIBRARY_PATH'}
  Only look for the sh script mysql_fix_privileges when not on windows
  Remove warnings about using unitialized variables
  Improve the restart logic, eall code to determine when to restart is
  now in run_testcase_need_master_restart and run_testcase_need_slave_restart
mysql-test/t/bdb-alter-table-2-master.opt:
  Use --force-restart
mysql-test/t/not_embedded_server-master.opt:
  Use --force-restart
