1. PostCodeLib.

Browse Source 
Rename BasePostCodeLib80 to BasePostCodeLibPort80. 
		Fix typos in macro POST_CODE() and POST_CODE_WITH_DESCRIPTION()
	2. DebugLib
		Change the parameter type of LineNumber of DebugAssert() from “INTN” to “UINTN” to follow MWG.
		Add type cast “(EFI_GUID *)” in macro ASSERT_PROTCOL_ALREADY_INSTALLED () to follow MWG.
	3. BasePeCoffLib/
		Add library function header for all the interfaces in MWG.
		Add missing ASSERT()s.
	4. PciLib
		Add ASSERT()s in PciRead/WriteBuffer() to check cross PCI function access.
