Current hcd-ohci does not handle DMA errors. However they may happen
so here we introduce simple error handling.
On such errors, a typical OHCI will stop operating, signal the guest
about the error by sending "UnrecoverableError Event", set itself into
error state and set "Detected Parity Error" in its PCI config space
to signal that it got an error and so does the patch.
This also adds ohci_die() call to ohci_bus_start() to handle possible
failure of qemu_new_timer_ns().

Spice has two display interface implementations: One integrated into
the qxl graphics card, and one generic which can operate with every
qemu-emulated graphics card.
The generic one is activated in case spice is used without qxl. The
logic for that only caught the "-vga qxl" case, "-device qxl-vga" goes
unnoticed. Fix that by adding a check in the spice interface
registration so we'll notice the qxl card no matter how it is created.

It appears that even a very simple /etc/qemu-ifup configuration can

A previous commit, "seccomp: add the asynchronous I/O syscalls to the
whitelist", added several asynchronous I/O syscalls but left out the
io_submit() and io_cancel() syscalls. This patch corrects this by
adding the two missing asynchronous I/O syscalls.

Rephrase code used in ARM sigreturn functions to avoid using
uninitialized variables. This fixes one genuine problem ('frame'
would not be initialized if we took the error-exit path because
our stackpointer was misaligned) and one which is clang being
alarmist (frame_addr wouldn't be initialized, though this is
harmless since unlock_user_struct ignores its second argument
in these cases; however since we don't generally make use of
this not-really-documented effect it's better avoided).

Silence a clang warning in a PPC signal return function:
/home/petmay01/linaro/qemu-from-laptop/qemu/linux-user/signal.c:4611:9: error: variable 'sr_addr' is used
uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
if (!lock_user_struct(VERIFY_READ, sc, sc_addr, 1))
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/home/petmay01/linaro/qemu-from-laptop/qemu/linux-user/signal.c:4636:28: note: uninitialized use occurs here
unlock_user_struct(sr, sr_addr, 1);
^~~~~~~
/home/petmay01/linaro/qemu-from-laptop/qemu/linux-user/qemu.h:442:27: note: expanded from macro 'unlock_user_struct'
unlock_user(host_ptr, guest_addr, (copy) ? sizeof(*host_ptr) : 0)
^
This happens when we unlock a user struct which we never
attempted to lock. Strictly, clang is actually wrong here -- it
hasn't been able to spot that unlock_user_struct() doesn't use
its second argument if the first is NULL. However it doesn't
seem too unreasonable to demand that we pass in initialized
values to it.

It turns out that some 32 bit windows guests crash
if 64 bit PCI hole size is >2G.
Limit it to 2G for piix and q35 by default.
User may override default 64-bit PCI hole size by
using "pci-hole64-size" property.
Examples:
-global i440FX-pcihost.pci-hole64-size=4G
-global q35-pcihost.pci-hole64-size=4G
