* fix(rowgroup): RGData now uses uint64_t counter for the fixed sizes columns data buf.
The buffer can utilize > 4GB RAM that is necessary for PM side join.
RGData ctor uses uint32_t allocating data buffer.
This fact causes implicit heap overflow.
* feat(bytestream,serdes): BS buffer size type is uint64_t
This necessary to handle 64bit RGData, that comes as
a separate patch. The pair of patches would allow to
have PM joins when SmallSide size > 4GB.
* feat(bytestream,serdes): Distribute BS buf size data type change to avoid implicit data type narrowing
* feat(rowgroup): this returns bits lost during cherry-pick. The bits lost caused the first RGData::serialize to crash a process
ColumnStore now uses standard bin/lib paths for pretty much everything.
Data path is now hard-coded to /var/lib/columnstore.
This patch also:
* Removes v1 decompression
* Removes a bunch of unneeded files
* Removes COLUMNSTORE_INSTALL_DIR / $INSTALLDIR
* Makes my.cnf.d work for all platforms (MCOL-3558)
* Changes configcpp to use recursive mutex (fixes possible config write deadlock)
* Fixes MCOL-3599 Fix regr functions, The library was installed in the wrong location
* Fixes a bunch of Ubuntu packaging issues
* Changes the binary names of several of the executables so as not to
clash with potential executables from other packages
