[MEDIUM] Create new protected pattern types CONSTSTRING and CONSTDATA to force memcpy if data from protected areas need to be manipulated.
Enhance pattern convs and fetch argument parsing, now fetchs and convs callbacks used typed args.
Add more details on error messages on parsing pattern expression function.
Update existing pattern convs and fetchs to new proto.
Create stick table key type "binary".
Manage Truncation and padding if pattern's fetch-converted result don't match table key size.
