Remove useless belt and suspenders include guards in some of our headers.

For these headers:

/usr/include/machine/atomic.h
/usr/include/machine/bus_dma.h
/usr/include/machine/coredump.h
/usr/include/machine/cpufunc.h
/usr/include/machine/db_machdep.h

/usr/include/machine/trap.h
/usr/include/machine/tss.h
/usr/include/machine/ucontext.h
/usr/include/machine/vframe.h
/usr/include/machine/vm86.h

All these headers #define _CPU_... and not _MACHINE_... even though they
are in /usr/include/machine. And the headers themselves have include
guards already. So there's little point in having them around the actual
#include additionally.

rename amd64 architecture to x86_64

The rest of the world seems to call amd64 x86_64. Bite the bullet and
rename all of the architecture files and references. This will
hopefully make pkgsrc build

Revert "rename amd64 architecture to x86_64"

This reverts commit c1543a890188d397acca9fe7f76bcd982481a763.

I'm reverting it because:
1) the change didn't get properly discussed
2) it was based on false premises:
"The rest of the world seems to call amd64 x86_64."
3) no pkgsrc bulk build was done to test the change
4) the original committer acted irresponsibly by committing
such a big change just before going on vacation.

AMD64 - Sync AMD64 support from Jordan Gordeev's svn repository and
Google SOC project. This work is still continuing but represents
substantial progress in the effort.

With this commit the world builds and installs, the loader is able to
boot the kernel, and the kernel is able to initialize, probe devices, and
exec the init program. The init program is then able to run until it hits
its first fork(). For the purposes of the GSOC the project is being
considered a big success!

The code has been adapted from multiple sources, most notably Peter Wemm
and other peoples work from FreeBSD, with many modifications to make it
work with DragonFly. Also thanks go to Simon Schubert for working on gdb
and compiler issues, and to Noah Yan for a good chunk of precursor work
in 2007.

While Jordan wishes to be modest on his contribution, frankly we would
not have been able to make this much progress without the large number
of man-hours Jordan has dedicated to his GSOC project painstakingly gluing
code together, tracking down issues, and progressing the boot sequence.
