Adding Simple Pointer, GOP, SimpleTextInEx, and Networking protocols to the emulator. Cleaned up POSIX include situation by centralizing it in a single file, like NT32. Fixed TPL issue with TPL High not being emulated correctly, it was possible to take a timer tick when the locks in the DXE core should have prevented this. Remove some unused files to make things easier to maintain.
