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.

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.
