This fixes a crash in hot-unplug of virtio-pci devices behind a PCIe
switch. The crash happens because the ioeventfd is still set whent the
child is destroyed (destruction happens in postorder). Then the proxy
tries to unset to ioeventfd, but the virtqueue structure that holds the
EventNotifier has been trashed in the meanwhile. kvm_set_ioeventfd_pio
does not expect failure and aborts.
The fix is simply to move parts of uninitialization to a new
device_unplugged callback, which is called before the child is destroyed.

Right now we have these pairs:
- virtio_bus_plug_device/virtio_bus_destroy_device. The first
takes a VirtIODevice, the second takes a VirtioBusState
- device_plugged/device_unplug callbacks in the VirtioBusClass
(here it's just the naming that is inconsistent)
- virtio_bus_destroy_device is not called by anyone (and since
it calls qdev_free, it would be called by the proxies---but
then the callback is useless since the proxies can do whatever
they want before calling virtio_bus_destroy_device)
And there is a k->init but no k->exit, hence virtio_device_exit is
overwritten by subclasses (except virtio-9p). This cleans it up by:
- renaming the device_unplug callback to device_unplugged
- renaming virtio_bus_plug_device to virtio_bus_device_plugged,
matching the callback name
- renaming virtio_bus_destroy_device to virtio_bus_device_unplugged,
removing the qdev_free, making it take a VirtIODevice and calling it
from virtio_device_exit
- adding a k->exit callback
virtio_device_exit is still overwritten, the next patches will fix that.

Similar to the PCI bug that prompted these patches, virtio-ccw will
segfault after the reworking of hotplug/hot-unplug. Prepare for
this by moving virtio_ccw_stop_ioeventfd to before the freeing
of the proxy device.
A better place for this could be the device_unplugged callback
for the virtio-ccw bus. However, we do not yet have a callback
that works: this patch avoids the problem while leaving the tree
bisectable.

The default granularity for the FIT timer on 440 is on every 0x1000th
transition of TB from 0 to 1. Translated that means 48828 times a second.
Since interrupts are quite expensive for 440 and we don't really care
about the accuracy of the FIT to that significance, let's force FIT and
WDT to at best millisecond granularity.
This basically restores behavior as it was in QEMU 1.6, where timers
could only deal with millisecond granularities at all.
This patch greatly improves performance with the 440 target and restores
roughly the same performance level that QEMU 1.6 had for me.

Today we fire FIT and WDT timer events every time the respective bit
position in TB flips from 0 -> 1.
However, there is no need to do this if the end result would be that
we're changing a TSR bit that is set to 1 to 1 again. No guest visible
change would have occured.
So whenever we see that the TSR bit to our timer is already set, don't
even bother to update the timer that would potentially fire it off.
However, we do need to make sure that we update our timer that notifies
us of the TB flip when the respective TSR bit gets unset. In that case
we do care about the flip and need to notify the guest again. So add
a callback into our timer handlers when TSR bits get unset.
This improves performance for me when the guest is busy processing things.

It is currently possible to specify things like:
-device e1000,netdev=foo,vlan=1
With this usage, whichever argument was specified last (vlan or netdev)
overwrites what was previousely set and results in a non-working
configuration. Even worse, when used with multiqueue devices,
it causes a segmentation fault on exit in qemu_free_net_client.

This causes two slight backwards-incompatibilities between "-M pc-1.5"
and 1.5's "-M pc":
(1) a fw_cfg file is removed with this patch. This is only a problem
if migration stops the virtual machine exactly during fw_cfg enumeration.
(2) after migration, a VM created without an explicit "-device pvpanic"
will stop reporting panics to management.
The first problem only occurs if migration is done at a very, very
early point (and I'm not sure it can happen in practice for reasonable-size
VMs, since it will likely take more time to send the RAM to destination,
than it will take for BIOS to scan fw_cfg).
The second problem only occurs if the guest panics _and_ has a guest
driver _and_ management knows to look at the crash event, so it is
mostly theoretical at this point in time.
Thus keep the code simple, and pretend it was never broken.

Upstream OpenBIOS now implements SBus probing in order to determine the
contents of a physical bus slot, which is required to allow OpenBIOS to
identify the framebuffer without help from the fw_cfg interface.
SBus probing works by detecting the presence of an FCode program
(effectively tokenised Forth) at the base address of each slot, and if
present executes it so that it creates its own device node in the
OpenBIOS device tree.
The FCode ROM is generated as part of the OpenBIOS build and should
generally be updated at the same time.

pc-bios/s390-zipl.rom is a flat image so it's expected that
loading it as elf will fail.
It should fall back on loading a flat file, but doesn't
on 32 bit systems, instead it fails printing:
qemu: hardware error: could not load bootloader 's390-zipl.rom'
The result is boot failure.
The reason is that a 64 bit unsigned interger which is set
to -1 on error is compared to -1UL which on a 32 bit system
with gcc is a 32 bit unsigned interger.
Since both are unsigned, no sign extension takes place and
comparison evaluates to non-equal.

This reverts commit cd5be5829c.
Digging into hardware specs shows this does not
actually make QEMU behave more like hardware:
There are valid arguments backed by the spec to indicate why the version
of e1000 prior to cd5be582 was more correct: the high byte actually
includes a valid bit, this is why all guests write it last.
For rtl8139 there's actually a separate undocumented valid bit, but we
don't implement it yet.
To summarize all the drivers we know about behave in one way
that allows us to make an assumption about write order and avoid
spurious, incorrect mac address updates to the monitor.
Let's stick to the tried heuristic for 1.7 and
possibly revisit for 1.8.

These are two patches that will hopefully make it into 1.7. The SLOF update
fixes -append kernel command line argument passing into the guest kernel. The
other patch makes VIO devices appear when using -device '?'.

$(PYTHON) is a Make variable which is set by configure.
In all other places over the tree, .py files are run from
Makefiles using this variable, except of a single leftover
in hw/i386/Makefile.obj (and a nearby place in there uses
$(PYTHON) correctly). Fix this leftover too.

The BIOS that we ship in 1.7 does not use pci info
from host and so far isn't going to use it.
Taking in account problems it caused see 9604f70fdf and
to avoid future incompatibility issues, it's safest to
disable that interface by default for all machine types
including 1.7 as it was never exposed/used by guest.
And properly remove/cleanup it during 1.8 development cycle.

This reverts PCI master abort support - we'll want it
eventually but it exposes too many core bugs to be safe for 1.7.
This also reverts a recent exec.c change that was an
attempt to work-around some of these core bugs.
Also included are small fixes in pc and virtio,
and a core loader fix for PPC bamboo.

Using multiple calls to error_report here means every line is
prefaced with the (potentially long) pci-assign command line
arguments.
Use a single error_printf to preserve the intended formatting.
Since this code path is always preceded by an error_report call,
we don't lose the command line reporting.
