BUG#32398 - Falcon: tablespace file can be table file
It was possible to create Falcon tablespace data files in
MySQL database directory with potential MyISAM/partitioning
index/data file names. Later MyISAM/partitioning may
silently overwrite Falcon tablespace data file.
E.g.:
CREATE TABLESPACE ts1 ADD DATAFILE 'test/t1.MYD' ENGINE=Falcon;
CREATE TABLE test.t1(a INT) ENGINE=MyISAM;
The second statement overwrites Falcon tablespace file.
The original patch for this bug was commented out some
time ago - it caused some problems and was considered
to be incorrect.
With this fix, when creating Falcon tablespace, we append
'.fts' extention to it's data file name if the provided
name doesn't end up with '.fts' already.

Updated test result.

Re-enabled falcon_bug_32398.

Reverted original (was already commented out) fix for BUG#32398.
Append '.fts' extention to tablespace data file name if the name
doesn't have it.
