This is "productization" of an old code that would enable extent
elimination for dictionary columns.
This concrete patch enables it, fixes perfomance degradation (main
problem with old code) and also fixes incorrect behavior of cpimport.
The charset default patch introduced a new unrelated default value for columnstore plugin
affecting bootstrap_mcs.sh fragile logic.

A new option is added (-n/--no-clean-install) that allows a user to
re-install ColumnStore without deleting the existing db files. This is
useful for testing new code changes in the engine without the need to
re-create the database tables to test the code changes.

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
This branch enforces the use of generic MariaDB server paths for their
binaries and data rather than custom paths.
/usr/local/mariadb/columnstore is now only for columnstore with this
patch.
It should be noted that this removes the auto-mounting of external
MariaDB UM data storage for AWS.
This is also a fix for MCOL-3510 after buildbot changes are made.
Also... MCOL-3552 Use columnstore.cnf to load plugins
The ColumnStore plugins now load using a columnstore.cnf instead of a
SQL sequence to be more in-line with MariaDB's methods.
This patch:
* Moves ColumnStore my.cnf to /etc/my.cnf.d/columnstore.cnf
* Removes unneeded entries from columnstore.cnf
* Removes some things that used my.cnf and are now dead
* Also removes utils/scenarios
* Modifies things that use extra defaults file to use the standard one
* Makes sure that C++11 standard is used for older CMake versions
With this patch we no longer need to set -DINSTALL_SYSCONF2DIR and
-DINSTALL_SYSCONFDIR when building MariaDB server.
