Remove FPU types from compat/ia32/ia32_reg.h that are no longer needed.
Create machine/npx.h on amd64 to allow compiling i386 code that uses
this header.
The original npx.h and fpu.h define struct envxmm differently. Both
definitions have been included in the new x86 header as struct __envxmm32
and struct __envxmm64. During compilation either __envxmm32 or __envxmm64
is defined as envxmm depending on machine architecture. On amd64 the i386
struct is also available as struct envxmm32.

usbdump stores data. Until this patch it was not possible
to exchange traces between 32-bit, 64-bit, big- and
little endian platforms. The problem is the dynamic nature
of the BPF timestamp in the header. All other fields are
fixed size and little endian.

For example, some BIOS for AMD SB600 south bridge may map HPET MMIO base
address as a memory BAR for SMBus controller depending on a PM register
configuration. Before r231161 (and r232086, subsequent MFC to stable/9),
it was not fatal but hpet(4) just failed to attach. Since we probe and
attach HPET earlier than PCI devices now, it caused unfortunate hard lockup.
With this patch, it does not hang any more and HPET works at the same time.
Clean up some style nits while I am in the neighborhood.

If the environment doesn't offer a working /dev/console, the existing
version of init(8) will simply refuse running rc(8) scripts. This means
you'll only have a system running init(8) and nothing else.
Change the code to do the following:
- Open /dev/console like we used to do, but make it more robust to use
O_NONBLOCK to prevent blocking on a carrier.
- If this fails, use /dev/null as stdin and /var/log/init.log as stdout
and stderr.
- If even this fails, use /dev/null as stdin, stdout and stderr.
So why us this useful? Well, if you remove the `getpid() == 1' check in
main(), you can now use init(8) inside jails to properly execute rc(8).
It still requires some polishing, as existing tools assume init(8) has
PID 1.
Also it is now possible to use use init(8) on `headless' devices that
don't even have a serial boot console.
If rc(8) is executed without using a TTY, this error appears at the
beginning:
stty: stdin isn't a terminal
Because this is to be expected and of course not harmful, it is better
to simply hide the error message.

Doomed vnode is hardly of any use here, besides all callers handle error

Don't mess with vnode holdcount, vget() takes care of it already.
