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.

+ Scans a target buffer for a 16-bit value, and returns a pointer to the matching 16-bit value

+ This function searches target the buffer specified by Buffer and Length from the lowest
+ address to the highest address for a 16-bit value that matches Value. If a match is found,
+ then a pointer to the matching byte in the target buffer is returned. If no match is found,
+ then NULL is returned. If Length is 0, then NULL is returned.
