Scott Graham fbe3cea201 Remove NString=80 limit
The parser now uses a vector to get tokens into, similar to how quoted strings
are handled. This buffer is PFn-scoped, so function and data parsing can use
it. Type parsing has to copy its names to the global heap.

While this avoids the "identifier too long" error, it of course calls malloc
more often, so could potentially have a small negative performance impact on
parsing.
