The idea is to add DEFINER-clause in CREATE PROCEDURE and CREATE FUNCTION
statements. Almost all support of definer in stored routines had been already
done before this patch.

NOTE: this patch changes behaviour of dumping stored routines in mysqldump.
Before this patch, mysqldump did not dump DEFINER-clause for stored routines
and this was documented behaviour. In order to get full information about stored
routines, one should have dumped mysql.proc table. This patch changes this
behaviour, so that DEFINER-clause is dumped.

Since DEFINER-clause is not supported in CREATE PROCEDURE | FUNCTION statements
before this patch, the clause is covered by additional version-specific comments.

if --skip-grant-tables specified.

The problem is that there is a check that prevents creating a definer
with empty host name.

In --skip-grant-tables mode this check prevents the user from creating a
trigger/view without explicitly specifying its definer. This happens, because
in --skip-grant-tables mode CURRENT_USER is ''@''. According to Sanja this
check was implemented intentionally.

However, according to the MySQL manual it is possible to specify empty host
name (as well as empty user name). Moreover, the behaviour for stored routines
is different in this aspect -- we allow them to be created with implicit
definer.

Based on this, we believe it is OK to change the behaviour for views to be
similar with the behaviour for stored routines.

The idea of the fix is to extend support of non-SUID triggers for backward
compatibility. Formerly non-SUID triggers were appeared when "new" server
is being started against "old" database. Now, they are also created when
"new" slave receives updates from "old" master.

bug #13525 "Rename table does not keep info of triggers".

Now we use MYSQLTEST_VARDIR in order to be able to run this test in different
vardir. Also improved cleanup after the test.

Let us transfer triggers associated with table when we rename it (but only if
we are not changing database to which table belongs, in the latter case we will
emit error).
