MDEV-30619: Test case for MDEV-29639 SBM spike fix
Added test case to cover SBM spike of relay log read and LMT
update that was fixed by MDEV-29639
Note that pause_sql_thread_on_next_event usage was removed
with the MDEV-30619 fixes. Rather than remove it, we adapt it
to the needs of this test case.
Additionally updated rpl_seconds_behind_master_spike.test to
use the negate_clock_diff_with_master debug eval.
MDEV-30619: Parallel Slave SQL Thread Can Update Seconds_Behind_Master with Active Workers
If the workers of a parallel replica are busy (potentially with long
queues), but the SQL thread has no events left to distribute (so it
goes idle), then the next event that comes from the primary will
update mi->last_master_timestamp with its timestamp, even if the
workers have not yet finished.
This patch changes the parallel replica logic which updates
last_master_timestamp after idling from using sql_thread_caught_up
(added in MDEV-29639) to using rli queued/dequeued event counters.
That is, if the queued count is equal to the dequeued count, it
means all events have been processed and the replica is idle.

MDEV-30619: Rename rpl_delayed_parallel_slave_sbm to rpl_parallel_sbm
To make a more generalized test for Seconds_Behind_Master on
the parallel replica, rpl_delayed_parallel_slave_sbm.test
is renamed to rpl_parallel_sbm.test for this purpose.

MDEV-31118: Add Lintian overrides for false positives
MariaDB Compression pluging pacakages mariadb-plugin-provider-*
have only one shared object and those are not linked against
libc and it's intentional so supressing error
library-not-linked-against-libc
There is needed dependency for Systemd DH plugin which
makes error missing-build-dependency-for-dh-addon obsolette.
Reworked debian/control that makes most of
version-substvar-for-external-package error not correct
so remove those that are not available anymore and update
those that are still relevant.
NOTE TO MERGER: This is only up-to MariaDB 10.10.

MDEV-31118: Override lintian dh-addon for systemd
Lintian erros with

One of these premises should be installed:
debhelper:any (>= 9.20160709~)
debhelper-compat:any
dh-sequence-systemd:any
dh-systemd:any
As there is package debhelper version 10 or higher required
for build. This is false positive Lintian error which should
be supressed..

In debian/control file there is several mariadb-*-10.9 Conflicts
or Replaces that which are not neede on MariaDB 10.9 anymore
as there is not suffix anymore.
Package libmariadbclient-dev is part of Ubuntu and it's
not build with official package so there can't be
variable: '${source:Version}' which is used with packages
that are part of package.
