Post automerge correction.

  Added the code processing on expressions for applying
  multiple equalities.

  Post-merge fixes for Item_equal patch.

  Fixed a problem when an equality field=const cannot be applied to
  the predicate P(field,c) for constant propagation as a conversion
  of field is needed.

test results corrected

into serg.mylan:/usr/home/serg/Abk/mysql-5.0

  Change parsing of @image argument.

NO SQL
CONTAINS SQL (default)
READS SQL DATA
MODIFIES SQL DATA

These are needed as hints for the replication.
(Before this, we did have the default in the mysql.proc table, but no support in the parser.)

into mysql.com:/home/timka/mysql/src/5.0-1724

fix privileges for old style privileges tables on fly (as it do mysql_fix_privilege_tables dut if we have not it run)
fixed forgoten test

showing table type now is controled by new parameter 'FULL' of SHOW TABLES command (SHOW FULL TABLES) (as it was decided on last dev conf)

prevent filling temporary tables of views on list fields command

into sanja.is.com.ua:/home/bell/mysql/bk/work-error-5.0

fixed incorrect type custing (fixed problem with runing tests with --debug (thanks, Sergei Gluhov spoted it))

Fixed small error in new .FRM parser which caused it to handle 
improperly escaped strings.

into sanja.is.com.ua:/home/bell/mysql/bk/work-error-5.0

Portability fix (Got different results for double -> longlong when compiling with full optimization)

into sanja.is.com.ua:/home/bell/mysql/bk/work-error-5.0

Now simply give an error if no database. (The "global SP feature" will be
done using PATH instead.)

fixed ALTER VIEW syntax
fixed WITH CHECK OPTION clause printing in SHOW CREATE VIEW

now default behaviour do not prevent any updates of view.
Also updating VIEWs of queries without LIMIT clause will not be checked at all (there will not be even warning)
(changes according to discussion on last dev-conf)

  Added a test case for bug #5896.
sql_select.cc:
  Fixed the problem of ignoring on expressions depending
  only on outer table when outer table either contains
  1 row or is guaranteed to return only 1 row (bug #5896).
