* A more dynamic binlog format which allows small changes (1064)
* Log session variables in Query_log_event (1063)
It contains a few bugfixes (which I made when running the testsuite).
I carefully updated the results of the testsuite (i.e. I checked for every one,
if the difference between .reject and .result could be explained).
Apparently mysql-test-run --manager is broken in 4.1 and 5.0 currently,
so I could neither run the few tests which require --manager, nor check
that they pass nor modify their .result. But for builds, we don't run
with --manager.
Apart from --manager, the full testsuite passes, with Valgrind too (no errors).
I'm going to push in the next minutes. Remains: update the manual.
Note: by chance I saw that (in 4.1, in 5.0) rpl_get_lock fails when run alone;
this is normal at it makes assumptions on thread ids. I will fix this one day
in 4.1.

sql/log.cc:
Ensure that the Format_desc propagated on next relay logs does not trigger
undue actions (like incrementing some positions or clearing some files).
sql/log_event.cc:
* When the slave SQL thread finds a Rotate/Format_desc/Stop in the middle of
a transaction (then these were written by the slave itself to its relay log),
it should not increment rli->group* variables, but only rli->event* ones.
* When the slave SQL thread finds a Format_desc not to be ignored (not
the same server id as the slave's), if it has log_pos==0 it must not trigger
"unfinished transaction in master's binlog" (log_pos==0 is always a marker
in the relay log to mean "this event was not at this place in the master's
binlog": it's for fake Rotate events, and for Format_description events which the master had
to send us for replication to start).
* In the Query_log_event on disk, catalog is now terminated by '\0'.
* thd->catalog must be set to 0 when some exec_event() terminate (otherwise
double free).
sql/slave.cc:
* Fixes for a few bugs when ignoring events in the slave SQL thread:
- do not decrement rli->slave_skip_counter if the event is an event
related to the binlog or relay log itself (FORMAT_DESCRIPTION,
ROTATE, STOP) because these events should never be skipped (or the slave
will be confused). Usually the user wants to skip a query, not a Rotate...
- when we (re)connect to the master, we must free description_event_for_queue
(otherwise memory leak when we reconnect).
* Changed a bit the code where we change description_event_for_queue,
to make it look "safer".
* Moved 'created=0' to log.cc where it is safer.
* When the slave SQL thread finds a Rotate/Format_desc/Stop in the middle of
a transaction (then these were written by the slave itself to its relay log),
it should not increment rli->group* variables, but only rli->event* ones.
