    Last part of WL#1062: better replication of timezones: no more use · 61eb9e40

    of SET ONE_SHOT; storing tz info directly in event (if this info is needed),
    it's now allowed to have different global tz on master and slave.
    
    
    client/mysqlbinlog.cc:
      we need MAX_TIME_ZONE_NAME_LENGTH when processing log_event.h, and it's declared in mysql_priv.h
    mysql-test/r/rpl_timezone.result:
      result update
    mysql-test/t/rpl_timezone-slave.opt:
      Now that we can have different global value of timezone on master and slave, let's test it.
    mysql-test/t/rpl_timezone.test:
      Tests of the new replication of timezones: checking the output of mysqlbinlog,
      replication of CONVERT_TZ().
    sql/ha_innodb.cc:
      No very fast shutdown on Netware (anyway it's disabled on all platforms,
      but this is so that we don't forget to keep it disabled on Netware in the future).
    sql/log.cc:
      No more need to write SET ONE_SHOT to binlog for character set and timezone
      (as we store this info  directly nin the Query_log_event now).
    sql/log_event.cc:
      Exclude ::write() methods if MYSQL_CLIENT.
      Storing timezone info in the Query_log_event in master. Re-reading it in slave.
      Small code cleanups. I plan to not store the end 0 of catalog in binlog
      events soon.
    sql/log_event.h:
      replication of time zones: a place for tz info in Query_log_event,
      in LAST_EVENT_INFO. Plus if we are compiling a client, we don't need
      the ::write() methods, so keeping them out (of mysqlbinlog.cc;
      keeping them in, resulted in problem that mysqlbinlog does not know Timezone
      structure).
    sql/mysql_priv.h:
      moving this define from tztime.h (tztime.h has things which are
      too much for a client like mysqlbinlog).
    sql/set_var.cc:
      It's now allowed to change global value of charset or timezone even if using binlogging
      or if being a slave.
      Making CONVERT_TZ(,,@@session.time_zone) replicate.
    sql/set_var.h:
      these ::check()s are not needed anymore (changing global charset
      or timezone is now allowed even if binlogging or slave)
    sql/slave.cc:
      No more need to check for same global timezone if master is 5.x
      (ok, strictly speaking if it is > 5.0.3 but this is alpha).
    sql/slave.h:
      a function to wrap settings of charset to default.
    sql/tztime.cc:
      Adaptation of my_tz_find() to the case where it's not called from inside
      a query (i.e. cannot join its tz tables to the query's ones): this variant
      opens the tz tables itself, reads from them, and closes them. This is presently
      only used by the slave SQL thread (when it sets the tz before executing a query).
    sql/tztime.h:
      declaration of new function, plus moving symbol to mysql_priv.h
      for easier usage in mysqlbinlog (Dmitri, pardon me).
