Randy Heit 1eb7912bd8 - Make the autosegs read-only.
- Derive PClass from dobject.cpp. This has one major ramification: Since the PClass
  is not allocated until runtime, you cannot initialize any static/global data
  structures with pointers to PClasses using RUNTIME_CLASS. Attempting to do so
  will just initialize with a NULL pointer. Instead, you can initialize using
  the address of the pointer returned by RUNTIME_CLASS and dereference that. By
  the time you have an opportunity to dereference it, it will no longer be NULL.
- Sync CmakeLists.txt.
- Random fixes for problems GCC spotted.
