This is a preparatory commit for MDEV-35109 to make its
testing code cleaner (and harden other tests too).
The DEBUG_DBUG point simulate_delay_semisync_slave_reply
up to this patch used my_sleep() to delay an ACK response,
but sleeps are prone to test failures on machines that
run tests when already having a heavy load (e.g. on
buildbot).
This patch changes this DEBUG_DBUG sleep to use DEBUG_SYNC
to coordinate exactly when a slave should send its reply,
which is safer and faster.
As DEBUG_SYNC can't be used while a server is shutting
down, to synchronize threads with SHUTDOWN WAIT FOR SLAVES
logic, we use and extend wait_for_pattern_in_file.inc to
wait for an informational error message in the logic to
indicate that the shutdown process has reached the
intended state (i.e. indicating that the shutdown has
been delayed to await semi-sync ACKs). Specifically, the
extensions are as follows:
1. wait_for_pattern_in_file.inc is extended with parameter
wait_for_pattern_count as a number that indicates the
number of times a pattern should occur in the file before
return control back to the calling script.
2. search_for_pattern_in_file.inc is extended with parameter
SEARCH_ABORT_IS_SUCCESS to inverse the error/success
logic, so the SEARCH_ABORT condition can be used to
indicate success, rather than error.
