they are lying. nokia has no copyright on this code. and the double
license in a single file looks weird. that's why we moved it to
3rdparty/, so it is clear it is not nokia's.

Removed CPLUSPLUS_BEGIN/END_NAMESPACE & co and made it possible to compile the parser with CPLUSPLUS_WITHOUT_QT.

Things you mustn't do:
1) end an enum with a comma

2) #include <cxxxx> and not use std::

3) use anonymous structures

All three things are invalid C++. Anonymous structures inside
anonymous unions are allowed by GCC, but that doesn't mean it's valid.
