Added sql_mode PAD_CHAR_TO_FULL_LENGTH (WL#921) 

This pads the value of CHAR columns with spaces up to full column length (according to ANSI)
It's not makde part of oracle or ansi mode yet, as this would cause a notable behaviour change.
Added uuid_short(), a generator for increasing 'unique' longlong integers (8 bytes)
