Currently, after a migration qemu sends a broadcast packet to update
switches' MAC->port mappings.
Unfortunately, it picks a random (constant) ethertype and crosses its
fingers that no one else is using it.
This patch causes it to send a RARP packet instead. RARP was chosen for
2 reasons. One, it is always harmless, and will continue to be so even
as new ethertypes are allocated. Two, it is what VMware ESX sends, so
people who write filtering rules for switches already know about it.
I also changed the code to send SELF_ANNOUNCE_ROUNDS packets, instead of
SELF_ANNOUNCE_ROUNDS + 1, and added a simple backoff scheme.

That patch didn't seem to help on OpenBSD so I now finally got around
making another one that just emits the bytes of the offending insn
instead so people can keep using old assemblers:

When using Linux AIO raw still falls back to POSIX AIO sometimes, so we should
initialize it.
Not initializing it happens to work if POSIX AIO is used by another drive, or
if the format is not specified (probing the format uses POSIX AIO) or by pure
luck (e.g. it doesn't seem to happen any more with qcow2 since we have re-added
synchronous qcow2 functions).

0) This is an attempt to get an issue in usb-linux.c, for which a patch
was posted about a year ago, finally fixed.
1) Mark Burkley submitted a "EHCI emulation module" for review in in
October 2008 (see:
http://lists.gnu.org/archive/html/qemu-devel/2008-10/msg01326.html). No
EHCI emulation module was ever committed to qemu.
2) Part of that (large) patch was a fix for a separate issue in
usb-linux.c. Max Krasnyansky has ACK'ed that fix (see:
http://lists.gnu.org/archive/html/qemu-devel/2008-11/msg00032.html).
3) I already asked whether this fix was ready to be committed in last
April (see:
http://lists.gnu.org/archive/html/qemu-devel/2009-04/msg01763.html)
4) Maybe submitting this fix as a separate patch (with a really long
commit message but without a Signed-off-by) and cc-ing everbody involved
will help if actually getting this issue fixed.

Current code is broken at least on recent compilers, comparison
between signed and unsigned types yield incorrect code and render
the neon shift helper functions defunct. This is the third revision
of this patch, casting all comparisons with the sizeof operator to
signed ssize_t type to force comparisons to be between signed integral
types.

All other bits except for the EN in the VFP FPEXC register are defined
as subarchitecture specific and real functionality for any of the
other bits has not been implemented in QEMU. However, current code
allows modifying all bits in the VFP FPEXC register leading to
problems when guest code is writing 1's to the subarchitecture
specific bits and checking whether the bits stay up to verify the
existence of functionality which in fact does not exist in QEMU.
This patch has been revised to include the same behavior change in
the gdb register write function.

In the existing code shift value is clobbered during the pass loop.
This patch changes the code so that it stores the intermediate
result in the target neon register directly and eliminates the need
to use a temporary to hold the intermediate value thus leaving the
shift value in the temporary variable intact. This is a new patch
in this version of the patch series.

lzcnt is a AMD Phenom/Barcelona added instruction returning the
number of leading zero bits in a word.
As this is similar to the "bsr" instruction, reuse the existing
code. There need to be some more changes, though, as lzcnt always
returns a valid value (in opposite to bsr, which has a special
case when the operand is 0).
lzcnt is guarded by the ABM CPUID bit (Fn8000_0001:ECX_5).
