This change is in preparation for additional changes to
the APICID functions that will come in a later patch.

Remove the last leftovers from the files. Move the ones
that are still used to the files they belong, the others
that grep can't reach, simply throw away.
Merge comments ontop of file and that's it: smpboot integrated

They are i386 specific (the x86_64 definitions live
elsewhere, and should remain there), so are enclosed around
an ifdef

This is a very large patch, because it depends on a lot
of auxiliary static functions. But they all have been modified
to the point that they're sufficiently close now. So they're just
merged in smpboot.c

After the inclusion, a lot of files needs fixing for conflicts,
some of them in the headers themselves, to accomodate for both
i386 and x86_64 versions.

Impressing friends is a very important thing.
Do it in a separate function to make it even more

setup_trampoline() looks very similar between architectures, and this
patch unifies them. The i386 version allocates bootmem memory, while
the x86_64 version uses a fixed address.
In this patch, we initialize the global trampoline_base to the x86_64 version,
and i386 allocation can later override it.
