[TRAFODION-2977] Fix issues with maximum key length detection
This set of changes fixes several minor bugs:
1. The key length limit that Trafodion imposes differed from the HBase
limit. They are now the same.
2. CREATE INDEX logic lacked a check on key length. This has now been added.
3. There was a typo in the message text for message 1141 preventing the
computed key length from being displayed. This has been fixed.
4. There was a bug in the generator where, if CREATE INDEX were allowed to
have a long key, we generated plans to populate that index that would overrun
their buffers, causing ESPs to core. This has been fixed; we now guarantee that
buffers are long enough for at least one row.
