tdf#146432: fix crash with REGEXP_REPLACE() executed in query editor to
MariaDB
See bt here:
https://bugs.documentfoundation.org/attachment.cgi?id=177292
Noticing:
warn:legacy.osl:7697:7697:connectivity/source/drivers/mysqlc/mysqlc_general.cxx:188:
mysqlToOOOType: unhandled case, falling back to VARCHAR
I found REGEXP_REPLACE returned a MYSQL_TYPE_LONG_BLOB and some locations
should be taught about it.
Also, let's also deal with MYSQL_TYPE_TINY_BLOB and MYSQL_TYPE_MEDIUM_BLOB
