MDEV-39673 group_concat ignores max_allowed_packet

GROUP_CONCAT is limited by group_concat_max_len,
but also, as a string function it must respect max_allowed_packet.

Let's introduce THD::gconcat_max_len() helper to simplify checks.

Also:
* make max group_concat_max_len value the same as max max_allowed_packet
* use the same MY_MIN((ulonglong) ..., UINT_MAX32) in
  Item_func_json_objectagg as in Item_func_group_concat
* use overflow-safe type for lengths in Item_func_quote
  (MAX_MAX_ALLOWED_PACKET is 1G so uint cannot overflow yet, but it's
  a fragile assumption)

MDEV-39648: wsrep_sst_rsync.sh: apply safe() to joiner-supplied parameters

Issue:
wsrep_sst_rsync.sh interpolated WSREP_SST_OPT_REMOTE_USER and
WSREP_SST_OPT_REMOTE_PSWD verbatim. Because both values originate from
the joiner side of the SST request, a newline in either could splice
an extra directive into the donor-written stunnel.conf (silently
downgrading peer-cert verification) or an extra line into the rsync
magic file. MDEV-39413 had introduced safe() for the same threat class
in wsrep_sst_mariabackup but did not extend it to the rsync script.

Solution:
Routing the rsync interpolations through safe() closes the gap, and
extending safe() to also reject tab and newline ensures multi-line
values cannot survive into a config-file heredoc.

MDEV-39492 Parallel Query: Study how to create worker threads

Introduces parallel_worker_threads variable to control the number
of worker threads created by a parallel execution query.

2 new files, sql_parallel_workers.h sql_parallel_workers.cc which
contain structures for the creation, management and deletion of
parallel worker threads (pwt_ in the name).  Main management
class created in the stack in JOIN::exec, implemented for the
top level select.

Current parallel_worker_thread_func sleeps for 10 seconds, generates
a warning, signals the main thread, sleeps 10 seconds, signals the
main thread again, sets it's finished flag and cleans it's THD.

The main thread loops through worker threads, looking for finished
thread and cleans them up if they have finished.
It then waits for a signal, then processes it's message queue.

The thread management data is allocated on the stack in JOIN::exec.
Everything else is allocated using my_malloc() and my_free().

Threads are registed in server_threads, so are visible in
information_schema.processlist and the show processlist command.

We check that a kill query on a parallel worker is passed onto it's
manager and the query is properly aborted, and that a kill connection
is handled properly in parallel_worker.test.

Fix test failure on galera_sst_mariabackup_encrypt_with_key_server

Joiner mariadbd exits when SST is aborted; the exit code varies by
platform (clean 0 on some systems, signalled 134 / 1 on others).

pkill exit code can also vary by platform (clean 0 on some systems,
signalled 1 others).
