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 git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@1103 6f19259b-4bc3-4df7-8a09-765794883524
