The constructor of Rotate_log_event used when we are rotating our binlog or
relay log, should not assume that there is a nonzero THD available.
For example, when we are reacting to SIGHUP, the THD is 0.
In fact we don't need to use the THD in this constructor;
we can do like for Stop_log_event, and use the minimal Log_event
constructor.
If we were allowed to put Unix-specific commands in the testsuite,
I'd add a test for this (<sigh>).


sql/log.cc:
  A comment to warn that thd can be 0.
  The part about LOG_EVENT_FORCED_ROTATE_F is just to avoid segfault;
  this flag is already removed in 4.1 anyway.
sql/log_event.cc:
  A comment.

we change THD::system_thread from a 'bool' to a bitmap to be able to
distinguish between delayed-insert threads and slave threads.
- Fix for BUG#1701 "Update from multiple tables" (one line in sql_parse.cc,
plus a new test rpl_multi_update.test). That's just adding an initialization.


sql/repl_failsafe.cc:
  comment to warn about this unused code
sql/slave.cc:
  Now thd->system_thread is a bitmap, not a bool.
sql/sql_class.h:
  'bool' for THD::system_thread is not accurate enough; sometimes we need
  to distinguish between delayed-insert threads and slave threads;
  so changing THD::system_thread to a bitmap (uint).
sql/sql_insert.cc:
  thd.system_thread is now a bitmap
sql/sql_parse.cc:
  We need to initialize thd->lex.select_lex.options in mysql_init_query();
  it's already initialized in dispatch_command() but replication calls
  mysql_parse() directly, thus bypassing dispatch_command().
  Not initing it here leads to a query influencing the next query,
  in the slave SQL thread.
  The initialization in dispatch_command() must be kept as this
  command uses the variable in tests, even when the command was not a
  query (i.e. when mysql_init_query() was not called).

The problem was that when the slave SQL thread reads a hot relay log (hot = the one being written to by the
slave I/O thread), it must have the LOCK_log. It already took it for read_log_event(), but needs
it also for check_binlog_magic().
This should fix all recently reported failures of the rpl_max_relay_size test in 4.1 and 5.0
(though the bug exists since 4.0, it showed up first in 5.0).

instead of Log_event::Log_event(THD*, ...) when the event is built in the master
to be written in the binlog.
Rand_log_event already used the good constructor, so there really is no reason
for Intvar_log_event to be an exception.
This fixes a test failure of last night (which appeared after I removed a useless
e.server_id=thd->server_id in log.cc; in fact this line was not useless because
it hid the bad constructor).
Replication tests pass, with Valgrind too.
