* 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.
* toCppCode for ParseTree and TreeNode
* generated tree is compiling
* Put tree constructors into tests
* Minor fixes
* Fixed parse + some constructors
* Fixed includes, removed debug and old data
* Hopefully fix clang errors
* Forgot an override
* More overrides
Added logical transformation of the execplan::ParseTrees with the taking out the common factor in expression of the form "(A and B) or (A and C)" for the purposes of passing a TPCH 19 query.

ARM platforms. This patch resolves this issue and unifies AUX column
processing at x86 and ARM using tempate class SimdProcessor.
The patch also replaces uint16_t mask previously used in column.cpp and
SimProcessor code with a native masks that platform uses, e.g. __m128i
or __m128 on x86 and variety of masks on ARM.
To unify the processing I introduced a new filtering Compare Operator - COMPARE_NULLEQ.
with a 'c1 IS NULL semantics'.
* more build dependencies
* fix for cmake < 3.11
It cannot do ADD_LIBRARY(... ALIAS ...) on IMPORTED targets
* another fix for cmake 3.10.2
It doesn't know about CMAKE_CXX_STANDARD=20,
let's add the correct flag manually
* gcc 8 on aarch64
utils/common/simd_arm.h:241:16: error: need ‘typename’ before ‘simd::TypeToVecWrapperType<T>::WrapperType’ because ‘simd::TypeToVecWrapperType<T>’ is a dependent scope
JobList low-level code relateod to primitive jobs now uses shared pointers instead of ByteStream refs talking to DEC
b/c same-node EM-PP communication now goes over a queue in DEC instead of a network hop.
PP now has a separate thread that processes the primitive job messages from that DEC queue.
Despite we have another number of tests in result, they all still run
gtests_add_test cannot parse TYPED_TEST_SUITE one by one and run them
in one bunch
operations + morsel size weight model to equally allocate CPU b/w parallel query morsels.
This patch delivers better parallel query timings distribution(timings graph resembles normal
distribution with a bigger left side thus more queries runs faster comparing with PrioThreadPool-based
single-node installation).

important implementation details
