clause is silently ignored

When symbolic links are disabled by command line option or
NO_DIR_IN_CREATE sql mode, CREATE TABLE silently ignores
DATA/INDEX DIRECTORY options.

With this fix a warning is issued when symbolic links are disabled.

(also fixes the bugs: Bug#29320, Bug#29493 and Bug#30536)

Problem: Partitioning did not handle unordered scans correctly
for engines with unordered read order.

Solution: do not stop scanning fi a recored is out of range, since
there can be more records within the range afterwards.

Note: this is the patch that fixes the bug, but since there are no
storage engines shipped with mysql 5.1 (falcon comes in 6.0) there
are no test cases (it is a separate patch that only goes into 6.0)

1. A bad error message was given when a MERGE table with an
   InnoDB child table was tried to use.

2. After selecting from a correct MERGE table and then altering
   one of the children to InnoDB, incorrect results were returned.

These bugs have been fixed with the patch for bug 26379 (Combination
of FLUSH TABLE and REPAIR TABLE corrupts a MERGE table).

For verification, I added the test case from the bug report.

Reverted log tables alteration.

INSERT/UPDATE against CSV table created by MySQL earlier than 5.1.23
with NULL-able column results in server crash in debug builds.

Starting with 5.1.23 CSV doesn't permit creation of NULL-able columns,
but it is still possible to get such table from older MySQL versions.

Fixed by removing excessive DBUG_ASSERT().

  - archive test/result adjusted.
  - OPTIMIZE/ANALYZE PARTITION EXTENDED test case added.

Some test cases were missing preparation to deal with failed
predecessor test cases.

Added preparation (drop table if exists) to some test cases.
