Don't make OLD_PASSWORD() a reserved word

  Disable PAGE_CUR_LE_OR_EXTENDS because it does not work for non-latin1 char sets now

  Clarify the meaning of HA_READ_PREFIX_LAST as a search flag. InnoDB assumed the meaning wrong.

Added lengths for all MYSQL_FIELD string parameters
Changed field length to 2 byte in .frm files

  Since MySQL uses HA_READ_PREFIX_LAST in a wrong place, we make InnoDB to convert it to a right search condition

Added ALL as parameter option for all group functions.
