Commit 3dd05c and subsequent ones introduced the use of the GNU
specific __attribute__((__unused__)), which breaks MSVC compilation...

I'll use this as a reminder that gnu-efi is compiled with more than
GNU toolchains, and that contributors might want to be careful about
adding GNU-specific extensions...

This patch does the following:
Create a new eficompiler.h header that sets all compiler-specific
options and extensions
Create a new EFI_UNUSED macro to be used in lieu of
__attribute__((__unused__)) and applies it to the relevant sources
Move the ALIGN(x) macro, previously defined in efisetjmp.h to the new header

Oh, and it also fixes a bunch of trailing whitespaces (because my code
editor is set to do just that by default).

Turns out we actually need setjmp in one of gnu-efi's prominent
users, and it seems to make more sense to put it here than in
the application.

Turns out we actually need setjmp in one of gnu-efi's prominent
users, and it seems to make more sense to put it here than in

All of these are derived from the Tiano code, but I re-wrote the
x86_64 one because we use the ELF psABI calling conventions instead
of the MS ABI calling conventions. Which is to say you probably
shouldn't setjmp()/longjmp() between functions with EFIAPI (aka
__attribute__((ms_abi))) and those without.
