Cleanups:

- Removed some QQ markers
- Removed some rows not compatible with valgrind 3.9.0
- Made mysql_install_db.sh more silent by default. --verbose now gives more information
- Added assert that auto-increment doesn't generate 0 (safety)
- Removed thd->set_time() in some places as it's set in init_for_queries()
- Fixed some --big tests in tokudb
- Fixed a bug in mysql_client_test.cc where sql_mode was not properly reset
