We no longer generate broken kernel-mode system call stubs.

We no longer generate broken kernel-mode system call stubs.
We now have per-architecture definition files, since stdcall differences between the architectures cannot be fixed (tried a combination of --kill-at, which is ignored, and -add-stdcall-alias and --enable-stdcall-fixup. This is the same problem that breaks MSVC builds, according to Alex.)
Fixed KeRaiseIrqlToSynchLevel.
Added an arm directory in /ke where we have all the stubs for non-implemented ARM routines. We can now build almost the entire kernel and link it.
We now use intrinsics to export the Interlocked* APIs, for the ARM build. Recommend doing this for x86 too.
Hal and bootvid build and link.
