binlog_row_binlog test gained some indeterministic checks with changes due to

ChangeSet@1.2309.1.12, 2006-09-12 15:42:13+02:00, guilhem@gbichot3.local +14 -0
  Fixing problems I identified in my auto_increment work pushed in July
  (as part of the auto_increment cleanup of WL #3146; ...
The problem is in that show binlog events in indeterministic, row events can be compressed,
so that 2 seconds original delay does not guard from inconsistency.

We syncronize test's current inserted rows counter with system insert delayed thread
per each query.

From another side there is no requirement for binlog to be event per row and then 
to verify if binlog has recorded what was recently inserted is better
via reading from it instead of 'show binlog events'. 


mysql-test/extra/binlog_tests/binlog_insert_delayed.test:
  removing sleeps, syncronizing with system delayed thread per each statement,
  note that an insert statement is performed atomically including writing to binlog,
  so that concurrent selects are waiting. That's why the wait macro is safe.
mysql-test/r/binlog_row_binlog.result:
  new result
mysql-test/include/wait_until_rows_count.inc:
  macro implements waiting until a targeted table has a prescribed rows number.

#
# SUMMARY
#
# Waits until SELECT count(*)-$count from $table returns zero
#
# USAGE
#
# Set vars like
# let $count=11;
# let $table=t1;
# # invoke the macro
# --include wait_until_rows_count.inc
#
# EXAMPLE
# extra/binlog/binlog_insert_delayed.test
#
#
# TODO: generalize up to wait_[until|while] with arbitrary select or even query and
# a condition to wait or get awakened
# It's impossible to implement such a "most" general macro without
# extending mysqltest. Just no way to pass a query as an argument and
# evaluate it here, like eval "$quuery". One is bound
# to specify it inside of the macro
--disable_query_log
let $wait_counter= 300; # max wait in 0.1 seconds
while ($wait_counter)
{
eval select count(*)-$count from $table into @rez;
let $rez=`select @rez`;
let $success=`SELECT @rez = 0`;
let $no_success=1;

}

if ($no_success)
{
