MDEV-30370 Fixing spider hang when server aborts

This is Kentoku's patch for MDEV-22979 (e6e41f04f4e + 22a0097727f),
which fixes 30370.

It changes the wait to a timed wait for the first sts thread, which
waits on server start to execute the init queries for spider. It also
flips the flag init_command to false when the sts thread is being
freed. With these changes the sts thread can check the flag regularly
and abort the init_queries when it finds out the init_command is
false. This avoids the deadlock that causes the problem in MDEV-30370.

It also fixes MDEV-22979 for 10.4, but not 10.5. I have not tested
higher versions for MDEV-22979.

A test has also been done on MDEV-29904 to avoid regression, given
MDEV-27233 is a similar problem and its patch caused the
regression. The test passes for 10.4-11.0.

However, this adhoc test only works consistently when placed in the
main testsuite. We should not place spider tests in the main suite, so
we do not include it in this commit. A patch for MDEV-27912 should fix
this problem and allow a proper test for MDEV-29904. See comments in
the jira ticket MDEV-30370/29904 for the adhoc testcase used for this
commit.

MDEV-29199 Unique hash key is ignored upon INSERT ... SELECT into non-empty MyISAM table

disable bulk insert optimization if long uniques are used, because they
need to read the table (index_read) after every inserted now. And bulk
insert optimization might disable indexes.

bulk insert is already disabled in other cases when there are chances
that the table will be read duing the bulk insert.

MDEV-27631 Assertion `global_status_var.global_memory_used == 0' failed in mysqld_exit

plugin_vars_free_values() was walking plugin sysvars and thus
did not free memory of plugin PLUGIN_VAR_NOSYSVAR vars.

* change it to walk all plugin vars
* add the pluginname_ prefix to NOSYSVARS var names too,
  so that plugin_vars_free_values() would be able to find their
  bookmarks
