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.

UnixGopDriver.c

Abstract:
|
||||
|
||||
This file implements the EFI 1.1 Device Driver model requirements for UGA
|
||||
|
||||
UGA is short hand for Universal Graphics Abstraction protocol.
|
||||
|
||||
This file is a verision of UgaIo the uses UnixThunk system calls as an IO
|
||||
abstraction. For a PCI device UnixIo would be replaced with
|
||||
a PCI IO abstraction that abstracted a specific PCI device.
