Fix defines involving both literals and other defined macros.

We now store a list of tokens in our hash-table rather than a single
string. This lets us replace each macro in the value as necessary.

This code adds a link dependency on talloc which does exactly what we
want in terms of memory management for a parser.

The 3 tests added in the previous commit now pass.
