Removed cross references from PciCf8Lib and PciExpressLib class to PciLib class.
Added PeCoffLoaderGetMachineType to the PeCoffGetEntryPointLibrary Class. Document to be updated.
Added the PeCoffLoaderImageReadFromMemory() and PeCoffLoaderRelocateImageForRuntime () to the PcCoffLib.
Updated EfiImage.h and removed EFI_IMAGE_OPTIONAL_HEADER and EFI_IMAGE_NT_HEADERS as they were replaced with checking the MachineType.
PeCoffLib – Added checks for MachineType so the PeCoff lib can load any PE32 or PE32+ image. The relocations are still limited to IA32, X64, IPF, and EBC. I also added a re-relocator function to remove PeLoader Code from Runtime Lib. Even though there is only one instance of the re-relocator I wanted to get all the PeCoff loader code together.
Replaced DEBUG_CODE() macro with DEBUG_CODE_START() and DEBUG_CODE_END() so you can debug through the DEBUG_CODE() macros. Also removed PE/COFF code and replaced with library usage.
I also updated the IO Instrinsic lib to use _ReadWriteBarrior() to help with sync problems
