ANALYSIS:
=========
'CREATE TABLE' query with a large value for 'CONNECTION'
string reports an incorrect error.

The length of connection string is stored in .frm in two
bytes (max value= 65535). When the string length exceeds
the max value, the length is truncated to fit the two
bytes limit. Further processing leads to reading only a
part of the string as the length stored is incorrect. The
remaining part of the string is treated as engine type and
hence results in an error.

FIX:
====
We are now restricting the connection string length to 1024.
An appropriate error is reported if the length crosses this
limit.

NOTE:
=====
The 'PASSWORD' table option is documented as unused and
processed within a dead code. Hence it will not cause
similar issue with large strings.
