MCOL-271 empty strings should not be NULLs ( #2794 )
...
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.

Adding mcs_basic_types.h
...
For now it consists of only:
using int128_t = __int128;
using uint128_t = unsigned __int128;
All new privitive data types should go into this file in the future.

Fully resolve potentially ambiguous symbols by removing using namespace statements from headers which have a cascading effect. This causes potential behavior changes when switching to c++11 since symbols can be exported from std and boost while both have been imported into the global namespace.

MariaDB maps MEDIAN to PERCENTILE_CONT and also has PERCENTILE_DISC now.
