/** @file
Provides services to print debug and assert messages to a debug output device.
The Debug library supports debug print and asserts based on a combination of macros and code.
The debug library can be turned on and off so that the debug code does not increase the size of an image.
Note that a reserved macro named MDEPKG_NDEBUG is introduced for the intention
of size reduction when compiler optimization is disabled. If MDEPKG_NDEBUG is
defined, then debug and assert related macros wrapped by it are the NULL implementations.
