Initial suspend/resume support for amd64.

This code is heavily inspired by Takanori Watanabe's experimental SMP patch
for i386 and large portion was shamelessly cut and pasted from Peter Wemm's
AP boot code.

Introduce cpu_vendor_id and replace a lot of strcmp(cpu_vendor, "...").

Add missed parentheses

MFamd64: Break up the probe logic in the mem_drvinit routines so it's
a bit easier to parse.

Style(9) these files. No changes in the compiled code. (Verified by
diff'ing objdump -d output).

Fix copyright comment & FBSDID style nits.

Use __FBSDID().

Some BIOSs are using MTRR values that are only documented under NDA
to control the mapping of things like the ACPI and APM into memory.

The problem is that starting X changes these values, so if something
was using the bits of BIOS mapped into memory (say ACPI or APM),
then next time they access this memory the machine would hang.

This patch refuse to change MTRR values it doesn't understand,
unless a new "force" option is given. This means X doesn't change
them by accident but someone can override that if they really want
to.

Convert more malloc+bzero to malloc+M_ZERO.

Rename macros to all-uppercase. Get rid of a comment that was ironic
(I goofed on the bitshifts myself long ago ;) and a bit redundant:
code should be clear enough that it seldom needs comments at all.

Remove 42 unneeded #include <sys/ioccom.h>.

ioccom.h defines only implementation detail, and should therefore
only be included from the #include which defines the ioctl tags,
in other words: never include it from *.c

Set the bits in the mask from the left to the right, not backwards.

I missed a not. Also, remove invltlb(), since it's "unncessary [sic] because
wbinvd already flushes the the TLB."

K6-family MTRR support

This is tested, but I really can't say whether it works entirely. I
don't know exactly what to look for when testing it. So let's say this
is open for testing. Send any results to green@FreeBSD.org
