#74 [PATCH] Add AsciiPrint and AsciiVSPrint

[Pete Batard]

Per https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Library/PrintLib.h
AsciiPrint() is the official name of APrint() so declare it as such and define
an APrint alias for compatibility.

Note: We do it this way rather than declare a new AsciiPrint define because hooking into a variable argument function call is notoriously difficult to accomplish, and, if one wants to to do so in a library that can hook into either EDK2 or gnu-efi, having one using AsciiPrint() as a define whereas the other one uses an actual linkable function call requires the addition of a wrapper that is EDK2 vs gnu-efi aware. But if instead we do define the gnu-efi call to use the same AsciiPrint name as EDK2, no such wrapper is necessary.

Also add an AsciiVSPrint() to print a formatted ASCII string to a buffer using
a va_list. AsciiPrint() too is defined in EDK2's PrintLib.h, though our implementation
just invokes the Unicode version and then converts the buffer to ASCII.
