The problem was that the RETURNS column in the mysql.proc was of
CHAR(64). That was not enough for storing long-named datatypes.

The fix is to change CHAR(64) to LONGBLOB, and to throw warnings
at the time a stored routine is created if some data is truncated
during writing into mysql.proc.

  Update the ABI to reflect member rename

The problem is that currently there is no way to test the behavior
of the mysql_change_user() function using the mysqltest suite because
there is no internal command for it.

The solution is to introduce a change_user command that can be used
to test aspects of the MySQL client function mysql_change_user().


client/mysqltest.c:
  Add change_user command to mysqltest.

The embedded version of the server doesn't use column level grants, and 
the compile directive NO_EMBEDDED_ACCESS_CHECKS should be checked instead of
the redundant HAVE_QUERY_CACHE (which is always the case) to determine if 
column level grants should be compiled or not.


mysql-test/r/query_cache.result:
  Updated result file
mysql-test/r/query_cache_notembedded.result:
  Updated result file
mysql-test/t/query_cache.test:
  Moved test with GRANT to query_cache_notembedded test.
mysql-test/t/query_cache_notembedded.test:
  Moved test with GRANT to query_cache_notembedded test.
sql/sql_cache.cc:
  Changed the conditional compilation directive to only compile column level grant
  checks if NO_EMBEDDED_ACCESS_CHECKS isn't defined.

The root cause of the issue was that the CREATE FUNCTION grammar,
for User Defined Functions, was using the sp_name rule.
The sp_name rule is intended for fully qualified stored procedure names,
like either ident.ident, or just ident but with a default database
implicitly selected.

A UDF does not have a fully qualified name, only a name (ident), and should
not use the sp_name grammar fragment during parsing.

The fix is to re-organize the CREATE FUNCTION grammar, to better separate:
- creating UDF (no definer, can have AGGREGATE, simple ident)
- creating Stored Functions (definer, no AGGREGATE, fully qualified name)

With the test case provided, another issue was exposed which is also fixed:
the DROP FUNCTION statement was using sp_name and also failing when no database
is implicitly selected, when droping UDF functions.
The fix is also to change the grammar so that DROP FUNCTION works with
both the ident.ident syntax (to drop a stored function), or just the ident
syntax (to drop either a UDF or a Stored Function, in the current database)

If mysql_lock_tables fails because the lock was aborted, we need to
reset thd->some_tables_delete, otherwise we might loop indefinitely
because handler's tables are not closed in a standard way, meaning
that close_thread_tables() (which resets some_tables_deleted) is not
used.

This patch fixes sporadical failures of handler_myisam/innodb tests
which were introduced by previous fix for this bug.


sql/sql_handler.cc:
  Properly reset thd->some_tables_deleted if mysql_lock_tables
  fails for some reason.

Before this patch, failures to write to the log tables (mysql.slow_log
and mysql.general_log) were improperly printed (the time was printed twice),
or not printed at all.

With this patch, failures to write to the log tables is reported in the
error log, for all cases of failures.

"DECLARE CURSOR FOR SHOW ..." is a syntax that currently appears to work,
but is untested for some SHOW commands and does not work for other SHOW
commands.

Since this is an un-intended feature that leaked as a result of a coding bug
(in the parser grammar), the correct fix is to fix the grammar to not accept
this construct.

In other words, "DECLARE CURSOR FOR SHOW <other commands that don't work>"
is not considered a bug, and we will not implement other features to make all
the SHOW commands usable inside a cursor just because someone exploited a bug.
