1) Instead of making dbrm calls to writeVBEntry() per block,
we make these calls per batch. This can have non-trivial
reductions in the overhead of these calls if the batch size
is large.
2) In dmlproc, do not deserialize the whole insertpackage, which
consists of the complete record set per column, which would be
wasteful as we only need some metadata fields from insertpackage
here. This is only done for batch inserts at the moment, this
should also be applied to single inserts.
Found that the IDBDataFile path in BRM journal writing code needs to seek
to the end of the file before writing.
If save_brm is run (as it is during init), it truncates the journal file,
but the workernode retained its original offset, resulting in the front
of the file being 0-filled on the next journal write. Load_brm can't
load that.

Fixes:
* Irrelevant where conditions
* Irrelevant const
* A potential infinite loop in treenode
* Bad implicit case fallthroughs
* Explicit markings for required case fallthroughs
* Unused variables
* Unused function
Also disabled some warnings for now which we should fix later.
Rename packages to MariaDB-columnstore-engine, MariaDB-columnstore-libs
and MariaDB-columnstore-platform.
Also add the "columnstore-" prefix the the components so that MariaDB's
packaging system understands then and add a line to include them in
MariaDB's packaging.
In addition
* Fix S3 building for dist source build
* Fix Debian 10 dependency issue
* Fix git handling for dist builds
* Add support for MariaDB's RPM building
* Use MariaDB's PCRE and readline
* Removes a few dead files
* Fix Boost noncopyable includes
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
