WL#3949 Test should set binlog format dnamically

- Reorganize collect a little to make it easier to apply optimizations
  and settings to collected test cases.
- Add suite/rpl/combination file
- Rename include/set_binlog_format_x.inc to .sql since thay are run by "mysql"
 


mysql-test/include/set_binlog_format_mixed.sql:
  Rename: mysql-test/include/set_binlog_format_mixed.inc -> mysql-test/include/set_binlog_format_mixed.sql
mysql-test/include/set_binlog_format_row.sql:
  Rename: mysql-test/include/set_binlog_format_row.inc -> mysql-test/include/set_binlog_format_row.sql
mysql-test/include/set_binlog_format_statement.sql:
  Rename: mysql-test/include/set_binlog_format_statement.inc -> mysql-test/include/set_binlog_format_statement.sql
mysql-test/lib/mtr_cases.pl:
  Reorganize code to
   - collect a suite
   - multiply the tests in the suite with any combinations the suite has
   - optimize the suite by skipping test not supported with current settings
  Use My::Config to read combinations file in my.cnf file format, this
  allowas a "short name" to be used for the combination instead of
  the full name wich is set to the extra arguments the combination applies
  Add function 'print_testcase' that can be used to print the testcases
  during different stages of the collect phase
mysql-test/lib/mtr_report.pl:
  Print <testname> '<combination>' if combination is set
mysql-test/mysql-test-run.pl:
  Add comments, fix indentation
  Rename .in to .sql files
  Only set binlog format dynamicall for master, slav is always restarted
mysql-test/lib/My/Config.pm:
  New BitKeeper file ``mysql-test/lib/My/Config.pm''
mysql-test/suite/rpl/combinations:
  New BitKeeper file ``mysql-test/suite/rpl/combinations''
