This is a necessary preliminary step for making it play with psqlscan.l given the way I set up the lexer input-buffer sharing mechanism in commit 0ea9efbe9ec1bf07. I've not tried to make it *actually* reentrant; there's still some static variables laying about. But flex thinks it's reentrant, and that's what counts. In support of that, fix exprparse.y to pass through the yyscan_t from the caller. Also do some minor code beautification, like not casting away const.
