[PATCH 0/2] MdeModulePkg/EbcDxe: add EBC Debugger

[Pete Batard <pete@akeo.ie>]

The EBC Debugger [1], which was present in Tianocore [2], is an 
invaluable tool for EBC development.
This patch adds it back into the EDK2, allowing, for instance, the 
compilation of an AARCH64 EBC debugger.

Note 1: The patch is split in two, so that the changes to the existing 
EbcDxe code are clearer.

Note 2: The diff between the original and the new sources can be found 
at [3]. Most of the changes were for whitespaces/API names/compiler 
warnings, with the notable exception of:
- Bumping of the EBCdebugger version to 1.0.
- Dropping of the DebuggerConfiguration protocol (which would require 
introducing a new global GUID and protocol). I didn't see it as 
particularly useful to caary on and would rather see if there is actual 
demand for it, before adding it back.
- Add of an EFIAPI qualifier for most of the support functions, 
especially the ones dealing with VPrint() ouput. This is required to 
avoid garbage text output in some instances.
- Fixing of the erroneous display of 32 and 64 bit indexes in the 
disassembly.
- Replacement of one assignation with CopyMem() to avoid an intrinsic 
memcpy().

Note 3: I tested the debugger built for AARCH64 and X64 using gcc on 
Linux (Debian/Sid) as well as the one built for IA32 and X64 using 
VS2015 on Windows. I haven't tested an IA64 version for lack of a toolchain.
