DebugLib:

Fix a bug in PeiDxeDebugLibReportStatusCode: it should use gReportStatusCodeDebugType so that report status code infrastructure can correctly extract debug info.
	Fix functional and coding style issues in the three instances in EdkModulePkg, namely: EdkDxeDebugLibReportStatusCode, EdkUefiDebugLibStderr, EdkUefiDebugLibConout.
	DevicePathLib:
	Sync with MWG 0.57 and add new interface of CreateDevicePathNode(). All the function headers have been updated.
	PeiServicesLib:
	Adjust coding style and fix a minor comment error.
	PciLib:
	Adjust assert() condition to sync with MWG 0.57
	BaseMemoryLib:
	Adjust assert() for ScanMemXX (), ScanGuid()
	Rename UefiMemoryLib to DxeMemoryLib
	PrintLib:
	Change the return value of all print services to exclude the NULL-terminator.
	Misc:
	Slightly adjust the coding style in hob.c in PeiCore module.
