mdkinney 0803854bc1 Update DXE Core to be compatible with PI 1.2 SMM Drivers. 
PI 1.2 SMM Drivers are allowed to call UEFI/DXE services and Protocols from the entry point of the PI 1.2 SMM Driver.  These UEFI/DXE services and Protocols may directly or indirectly calls the UEFI Boot Services RaiseTPL() and RestoreTPL().  These UEFI Boot Services use the CPU Architectural Protocol to enable interrupts if the TPL level is below TPL_HIGH_LEVEL and enable interrupts of the TPL is at TPL_HIGH_LEVEL.  Interrupts should be masked while executing SMM drivers, so if a direct or indirect call to the UEFI Boot Service RestoreTPL() would enable interrupts, then an interrupt could be incorrectly delivered in SMM context.  

The solution is for the DXE Core to register for the PI 1.2 SMM Base2 Protocol.  If that protocol is present in the platform, then the DXE Core can use the SMM Base 2 Protocol's InSmm() function to determine if the platform is currently executing in SMM content.  If the current context is in SMM, then do not allow any requests to be forwarded to the CPU Architecture Protocol to enable interrupts.

qhuang8 f3f2e05db8 Clean up to update the reference of the these macros: 
EFI_SIGNATURE_16 -> SIGNATURE_16
  EFI_SIGNATURE_32 -> SIGNATURE_32
  EFI_SIGNATURE_64 -> SIGNATURE_64
  EFI_FIELD_OFFSET -> OFFSET_OF
  EFI_MAX_BIT      -> MAX_BIT
  EFI_MAX_ADDRESS  -> MAX_ADDRESS
These macros are not defined in UEFI spec. It makes more sense to use the equivalent macros in Base.h to avoid alias.

qhuang8 9c4ac31cca Clean up DxeCore to remove duplicate memory allocation & device path utility services in Library.c.DxeCore should use MemoryAllocationLib & DevicePathLib for these API. 
Minor cleanup the coding style: #include <DxeMain.h> should be changed to #include "DxeMain.h" since "DxeMain.h" is not pubic header fie.
