James Starr updated CALCITE-6573:
---------------------------------
Description:
Split the SqlValidatorImpl up into several parts:
* SqlValidatorImpl - A facade to maintain the existing API and orchestrate the
composition of the objects below.
* ScopeMap - Contains the data structures for mapping SqlNodes to scopes and
namespaces, along with relevant helper methods.
* SqlNodeValidator - Contains most of the methods currently prefixed with
validate.
* ScopePopulator - Contains the methods prefixed with register.
* NamespaceBuilder - Formalizes an implicit API for overriding namespace
creation.
Each child object will have factory that is configurable in
SqlValidatorImpl.Config to allow for downstream customizations.
