* feat(joblist,runtime): this is the first part of the execution model that produces a workload that can be predicted for a given query.
- forces to UM join converter to use a value from a configuration
- replaces a constant used to control a number of outstanding requests with a value depends on column width
- modifies related Columnstore.xml values
* 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
* Fix clang warnings
* Remove vim tab guides
* initialize variables
* 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length
* Fix ISO C++17 does not allow 'register' storage class specifier for outdated bison
* chars are unsigned on ARM, having if (ival < 0) always false
* chars are unsigned by default on ARM and comparison with -1 if always true
Raised the default for orderby threads from 4 to 16.
Removed if LIMIT check block in makeVtableModeSteps().
Removed a duplicate of TimeCompare class and methods.
MCOL-3536 Upmerged the change.
MCOL-894 Post review changes.
Uncomment if LIMIT check block in makeVtableModeSteps().
TupleAnnexStep dtor now uses vector::size() as a boundary.
