  1. sql: add plpgsql parser scaffold. 

    This commit adds the code generation portion of the parser.
The parser does not parse statements yet.
This commit also creates a base scanner struct so that the plpgsql
and sql scanner can share methods. The two scanners have their
own language specific scan methods.
