Meta Primitive Jobs, .e.g ADD_JOINER, LAST_JOINER stuck

Adds a special column which helps to differentiate data and rollups of
various depts and a simple logic to row aggregation to add processing of
subtotals.
CI ocassionaly stuck running test001 b/c PP threadpool endlessly reschedules
meta jobs, e.g. BATCH_PRIMITIVE_CREATE, which ByteStreams were somehow damaged or read out.

This patch:
1. Properly processes situation when pm join result count is exceeded.
2. Adds session variable 'columnstore_max_pm_join_result_count` to control the limit.
Current join pipeline is not designed to send a temporal result and
continue execution. RowGroup for large side is the same where we store
the matched rows, we cannot continue to iterate over it, requires a
proper refactoring.
As part of the charset support, a call to MY_INIT() was added at the
initialization of the above processes. This call initializes the MySQL
thread environment required by the charset library. However, the
accompanying my_end() call required to terminate this thread environment
was not added at the termination of these process, hence leaking
resources. As a fix, we move the MY_INIT() calls to the Child()
functions of these services and also add the missing my_end() call.
* Fixes of bugs from ASAN warnings, part one
* MQC as static library, with nifty counter for global map and mutex
* Switch clang to 16
* link messageqcpp to execplan
This patch improves handling of NULLs in textual fields in ColumnStore.
Previously empty strings were considered NULLs and it could be a problem
if data scheme allows for empty strings. It was also one of major
reasons of behavior difference between ColumnStore and other engines in
MariaDB family.
Also, this patch fixes some other bugs and incorrect behavior, for
example, incorrect comparison for "column <= ''" which evaluates to
constant True for all purposes before this patch.
Analyze needs to be completed differently than a normal query. In server, when an ANALYZE is seen, it calls init_scan() immediatly followed by end_scan(). This leaves the sqlfrontendsession (ExeMgr) in a state where it expects to return rows. This patch fixes end_scan to clean this up via reads and writes to get everything back in synch.
ANALYZE should display the number of rows to be displayed if the query were run normally. We have that information available, but no way to return it. A modification to server side to ask for that in the handler is required.
This patch also includes a beautification of sqlfrontsessionthread.cpp since it looked bad. The important change is at line 774
if (!swallowRows)
which short circuits the actual return of data
