Refactored SQL Column and Table structures to use space_def instead of native fields.
All temporal memory is allocated on region to prevent memory leaks and easely manage memory
with frequent insertions on SQL expression parsing.
Introduced space_def pointer in Expr instead of Table pointer.
The ResolveSelfReference function requires Table pointer to refer to, but it doesn't exist in our scenarios yet.
With correctly-initialized consistent space_def structure this would no problem.
This preliminary tasks should make able to move SQL Checks in Server code.
