Fix the code in Parser/ to also compile with C++. This was mostly casts for

malloc/realloc type functions, as well as renaming one variable called 'new'
in tokensizer.c. Still lots more to be done, going to be checking in one
chunk at a time or the patch will be massively huge. Still compiles ok with
gcc.
