Refactor Lexer to support an abstract InputSource class

This patch allows us to remove the fmemopen lex_string hack to support
parsing buffers. This will allow us to support mutliple sources such as
metadata imports etc. The patch here updates the parser to hold onto a
reference to the lexer rather than 'owning' the lexer which allows us to
decouple the move semantics here.

Fixes #1203 #1000
