This patch allows the following syntax to change the current
autoincrement value for the table:
ALTER TABLE table_name COMMENT='autoincrement=value';
Where "value" is the new integer to be used.
I_S.COLUMNSTORE_FILES returned bad filenames and NULL file sizes when
there are multiple nodes in a ColumnStore cluster
It adds an extra message call to the WriteEngine to get the file size
for that file. The I_S function will figure out which WriteEngine to
communicate with and get the file size details from it.
