clause server fires immediately after creating event and time between create and delete
event sometimes is enough for firing. So adding STARTS clause moves first execution in
future after drop of event
1. Added STARTS clause for CREATE EVENT.
2. Updated result file.

character_set_database !=character_set_server" is fixed.

This does not bring any contents changes, it is purely
metadata which are affected.

Details:

Even within 5.0, most of these changesets did not cause
file contents changes, because they were backports done
for the "service pack" builds of 5.0.66sp1 and 5.0.72sp1.

The "real" changesets are also already present in 5.1,
so this upmerge doesn't change any contents.

The only "real" changeset in 5.0 was a fix of the shell
scripts used to configure bdb (BerkeleyDB).
As we completele removed bdb from the 5.1 sources already,
the affected files are not present in the 5.1 source tree,
so this changeset also does not cause any contents changes.

this should not happen.

This is not the final merge of that release build, but we need early
access to these tool fixes (use of "awk" in the BDB configuration).

bug#33094: Error in upgrading from 5.0 to 5.1 when table contains
triggers
and
#41385: Crash when attempting to repair a #mysql50# upgraded table
with triggers.

Problem:
1. trigger code didn't assume a table name may have
a "#mysql50#" prefix, that may lead to a failing ASSERT().
2. "ALTER DATABASE ... UPGRADE DATA DIRECTORY NAME" failed
for databases with "#mysql50#" prefix if any trigger.
3. mysqlcheck --fix-table-name didn't use UTF8 as a default
character set that resulted in (parsing) errors for tables with
non-latin symbols in their names and definitions of triggers.

Fix:
1. properly handle table/database names with "#mysql50#" prefix.
2. handle --default-character-set mysqlcheck option;
if mysqlcheck is launched with --fix-table-name or --fix-db-name
set default character set to UTF8 if no --default-character-set
option given.

Note: if given --fix-table-name or --fix-db-name option,
without --default-character-set mysqlcheck option
default character set is UTF8.

rows events are not initialized, and cause some engines (innodb)

partition_innodb_semi_consistent.test, which was overlooked in the
innodb-5.1-ss3603 snapshot.

The problem is that the query cache stores packets containing
the server status of the time when the cached statement was run.
This might lead to a wrong transaction status in the client side
if a statement is cached during a transaction and is later served
outside a transaction context (and vice-versa).

The solution is to take into account the transaction status when
storing in and serving from the query cache.
