This test compares all of the default register values against the
spec.  It turns out we deviate in quite a few places.  These
places are really only visible to the BIOS though which is why
this hasn't created any problems.

The deviation actually happens in the core PCI layer so I suspect
it's not a simple fix if we really care to fix it.  For now, just

Using qemu_memalign only leaves the RAM zero by chance, because libc
will usually use mmap to satisfy our huge requests.  But memory will
not be zero when using MALLOC_PERTURB_ with a nonzero value.  In the
case of incoming migration, this breaks a recently-introduced
invariant (commit f1c72795, migration: do not sent zero pages in
bulk stage, 2013-03-26).

To fix this, use mmap ourselves to get a well-aligned, always zero
block for the RAM.  Mmap-ed memory is easy to "trim" at the sides.

This also removes the need to do something special on valgrind
(see commit c2a8238a, Support running QEMU on Valgrind, 2011-10-31),
thus effectively reverts that patch.

Reimplement usb-host on top of libusb.
Reasons to do this:

 (1) Largely rewritten from scratch, nice opportunity to kill historical
     cruft.
 (2) Offload usbfs handling to libusb.
 (3) Have a single portable code base instead of bsd + linux variants.
 (4) Bring usb-host support to any platform supported by libusbx.

For now this goes side-by-side to the existing code.  That is only to
simplify regression testing though, at the end of the day I want remove
the old code and support libusb exclusively.  Merge early in 1.5 cycle,
remove the old code after 1.5 release or something like this.

Thanks to qdev the old and new code can coexist nicely on linux.  Just
use "-device usb-host-linux" to use the old linux driver instead of the
libusb one (which takes over the "usb-host" name).

The bsd driver isn't qdev'ified so it isn't that easy for bsd.
I didn't bother making it runtime switchable, so you have to rebuild
qemu with --disable-libusb to get back the old code.
