PCI address space is completely seperate, so we don't have to claim any
resources to avoid clashes with main memory and firmware. Makes accelerated
graphics work on the Tadpole SPARCLE.

privsep ( O_NONBLOCK | O_RDWR | O_EXCL) by turning the list of allowed
devices into a struct, with the flags we're supposed to use, then using
these values with open(). Add /dev/dri/card0 there too (more'll be needed to be
added when it matters).
This gives privsep with dri a chance to work.

CPUs in basic VESA mode:
X86EMU: handle CPUID instruction
Starting X on an AMD Geode LX system such as an Alix board with VGA
connector, the Xorg driver attempts to issue INT 10/0 to go to mode
3 (VGA). The emulator, running the BIOS code, would then spit out:
c000:0282: A2 ILLEGAL EXTENDED X86 OPCODE!
The opcode was 0F A2, or CPUID; it was not implemented in the
emulator. With this patch it handles the CPUID instruction in one of
two ways:
1) if ran on __i386__ or __x86_64__ then it calls the CPUID instruction
directly.
2) if ran elsewhere it returns a canned 486dx4 set of values for function 1.

This should fix hangs people were seeing with icewm, cwm and most
probably other WM under some circumstances.

each cmsg_len (ie. msg_controllen = sum of CMSG_ALIGN(cmsg_len). This
works now that kernel fd passing has been fixed to accept a bit of
sloppiness because of this ABI repair.
lots of discussion with kettenis. From deraadt@
Don't break grab and focus state for a window when redirecting it.
Composite uses an unmap/map cycle to trigger backing pixmap allocation
and cliprect recomputation when a window is redirected or unredirected.
To avoid protocol visible side effects, map and unmap events are
disabled temporarily. However, when a window is unmapped it is also
removed from grabs and loses focus, but these state changes are not
disabled.
This change supresses the unmap side effects during the composite
unmap/map cycle and fixes a bug where a compositing window manager
would cause the screensaver to lose its grab when it unredirects the
fullscreen lock window.
both the old i810 and the new intel drivers on i386, and let X
autoconfiguration code choose the one that is used based on the chipset.
Tested by landry@ and a few others.
