Since it is i386 specific, move it around an ifdef to
smpboot.c

With the previous changes, code for native_smp_prepare_cpus()
in i386 and x86_64 now look very similar. merge them into
smpboot.c. Minor differences are inside 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
explicit, and ease integration.

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.
