Merge with MySQL 5.1.50

- Changed to still use bcmp() in certain cases becasue
  - Faster for short unaligneed strings than memcmp()
  - Bettern when using valgrind
- Changed to use my_sprintf() instead of sprintf() to get higher portability for old systems
- Changed code to use MariaDB version of select->skip_record()
- Removed -%::SCCS/s.% from Makefile.am:s to remove automake warnings
