  Wrong handler.

crashes server." The fix makes Item_func_rand prepared-statements
aware plus it fixes the case when RAND is used in prepared
statements and replication is on (as well as several similar issues).
Until now we did not reset THD before every execution of a prepared
statement, so if some execution had set thd->time_zone_used
or thd->rand_used they would not be reset until next mysql_parse.
Some of post-review fixes done.

BUG#4335 - one name can be handler open'ed many times.
Fixed problems detected on Windows build by VC++.
Removed unused variables.
Applied a neccessary cast.

  Make checks (asserts) performed in client_test.c work in non-debug
  builds.

(bad merge from 4.0)

  Added catch for (example) WL#1234 into bk commit subjects

propogation works only once (prepared statements)".

- 'ps_10nestset' uses a "nested set" approach for an employee 
  hierarchy, then does arithmetic on the "salary" field;
  (soon) to be extended by inserts / deletes which imply
  mass updates on the "l"/"r" fields showing the set inclusion,
- 'ps_11bugs' will get (some of ?) those bug DB entries which
  refer to prepared statements, but whose number does not appear
  in a test file comment - so it will also be extended.

  A fix for Bug#6042 "constants propogation works olny once (prepared
  statements)": reset item->marker in Item::cleanup, as it's used
  in propogate_cond_constants. No test case as the only way I could
  come up with to show the problem is EXPLAIN, and EXPLAIN is painful
  to use in the test suite.

Fixes bug with tableImpl with blobs not being initialized properly w.r.t pointer to blob tableImpl in column
    added blob to test to see that blob tables don't show up in show tables
    auto increment setting need not fetch blob tables (will otherwise generate error during table creation)
    moved addBlobTables out of fetchGlobalTableImpl to get_local_table_info
    changed addBlobTables to start from last column and break if all blobs added
    also addBlobTables will return -1 if failed (typically getTable)
    changed to using get_local_table_info with internal table name where applicable for efficiency
    added option to get_local_table_info wether to fetch blob tables or not
    getTable always fetches the blobtables
    moved addBlobTables to get_local_table_info to always be called, even if main table goes to cache only
