On ia64 alignment requirements are strict. When we pass a pointer to
UUID it needs to be at least 4-byte aligned or EFI will crash.
On the other hand in device path there is no padding for UUID, so we
need 2 types in one formor another. Make 4-byte aligned and unaligned types
The code is structured in a way to accept unaligned inputs
in most cases and supply 4-byte aligned outputs.
Efiemu case is a bit ugly because there inputs and outputs are
reversed and so we need careful casts to account for this
inversion.

There are 3 implementations of a GUID in GRUB. Replace them with
a common one, placed in types.h.
It uses the "packed" flavor of the GUID structs, the alignment attribute
is dropped, since it is not required.

UEFI mandates MS calling convention on x86_64, which was not supported
on GCC when UEFI support was first introduced into GRUB. However, now we
can use the ms_abi function type attribute to annotate functions and
function pointers as adhering to the MS calling convention, and the
compiler will generate the correct instruction sequence for us.
So let's add the appropriate annotation to all the function prototypes.
This will allow us to drop the special call wrappers in a subsequent patch.
