            really damaged MyISAM tables

When unpacking a blob column from broken row server crash
could happen. This could rather happen when trying to repair
a table using either REPAIR TABLE or myisamchk, though it
also could happend when trying to access broken row using
other SQL statements like SELECT if table is not marked as
crashed.

Fixed ulong overflow when trying to extract blob from
broken row.

Affects MyISAM only.

Repair table could crash a server if there is not sufficient
memory (myisam_sort_buffer_size) to operate. Affects not only
repair, but also all statements that use create index by sort:
repair by sort, parallel repair, bulk insert.

Return an error if there is not sufficient memory to store at
least one key per BUFFPEK.

Also fixed memory leak if thr_find_all_keys returns an error.

            hangs on Linux

If REPAIR TABLE ... USE_FRM is issued for table that is located in different
than default database server crash could happen.

In reopen_name_locked_table take database name from table_list (user specified
or default database) instead of from thd (default database).

Affects 4.1 only.

Added proper casts

No test case. myisampack must be tested manually.

Examined rows are counted for every join part. The per-join-part
counter was incremented over all iterations. The result variable
was replaced at the end of every iteration. The final result was
the number of examined rows by the join part that ended its
execution as the last one. The numbers of other join parts was
lost.

Now we reset the per-join-part counter before every iteration and
add it to the result variable at the end of the iteration. That
way we get the sum of all iterations of all join parts.

No test case. Testing this needs a look into the slow query log.
I don't know of a way to do this portably with the test suite.
