Fixed new bug when reading field types

into narttu.mysql.fi:/my/mysql-4.1

  Changes according to CHARSET_INFO structure

  utf8 was not marked as compiled

into narttu.mysql.fi:/my/mysql-4.1

into mashka.mysql.fi:/home/my/mysql-4.1-narttu

  Remove accidenatlly committed debug printfs when query cache is used
sql_update.cc, sql_load.cc, sql_insert.cc, sql_delete.cc:
  For the transactional query cache algorithm to work we must invalidate the query cache in INSERT/DELETE/UPDATE before writing to the binlog or calling ha_autocommit_... Note that binlog writing may also call commit. The crucial thing is that the transaction which modified data must not be committed BEFORE the query cache is invalidated.

ctype_ucs2 and ctype_ujis were skipped in mistake

  cp1250_czech_ci was displayed even when not compiled-in in mistake.

  Character set in this test results was displayed dispite the fact that the table has the same character set

  c
Index.xml:
  Collation names form lati7 were mixed

  Bug fix: if latin2_czech_ci is not compiled, loader din't load other latin2 collations

Character set is not displayed in "Type" column anymore
In "Collation" column NULL instead of BINARY is now displayd for for non-character data types

into bar.mysql.r18.ru:/usr/home/bar/mysql-4.1

Collation and coercibility tests for string functions

into light.hegel.local:C:/mysql-dev/mysql-4.1

USER(), DATABASE() and VERSION() return in utf8 now

This is because rpl_relayrotate.test uses InnoDB.
Example of a failing sequence:
rpl_relayrotate.test repl_user_variables.test rpl_relayrotate.test
Explaination in the files.
Btw all other tests which use InnoDB (innodb*.test) already have this final
DROP TABLE.
Removed a wrong comment of mine.

  default_collation is now displayed correctly in mysqld --help
  mysqld --help now displays default_collation corretly, according to --default-character-set

Fixed that SHOW CHARACTER SET displayed non-dynamic charsets even if they were not really compiled

  Typos fixes

  Bug fix: latin1 is not compiled charset and is not specified..
mysql.cc:
  Bug fix: latin1 is not compiled charset and is not specified...

Added initialization of all important global variables

collation_client  -> character_set_client
collation_results -> character_set_results
character_set     -> character_set_server

SET NAMES now doesn't start client->server conversion
SET CHARACTER SET now starts both client->server and server->client conversion
