Regarding MERGE tables:
For now, the best option is to use the common TABLE *pointer for all
cases; The drawback is that for MERGE tables we will see many locks
for the merge tables even if some of them are for individual tables.
The way to solve this is to add to 'THR_LOCK' structure a pointer to
the filename and use this when printing the data.
(We can for now ignore this and just print the same name for all merge
table parts; Please add the above as a comment to the display_lock
function so that we can easily add this if we ever need this.
