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. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@757 6f19259b-4bc3-4df7-8a09-765794883524

Copies a source buffer to a destination buffer, and returns the destination buffer.

This function copies Length bytes from SourceBuffer to DestinationBuffer, and returns

where SourceBuffer overlaps DestinationBuffer.

If Length is greater than (MAX_ADDRESS - DestinationBuffer + 1), then ASSERT().
