pci_read_devaddr() is only used by the legacy functions for the old PCI

pci-hotplug.c and the CONFIG_PCI_HOTPLUG variable which controls its
compilation are misnamed. They're not about PCI hotplug in general, but
rather about the pci_add/pci_del interface which are now deprecated in
favour of the more general device_add/device_del interface. This patch
therefore renames them to pci-hotplug-old.c and CONFIG_PCI_HOTPLUG_OLD.
CONFIG_PCI_HOTPLUG=y was listed twice in {i386,x86_64}-softmmu.make for no
particular reason, so we clean that up too. In addition it was included in
ppc64-softmmu.mak for which the old hotplug interface was never used and is
unsuitable, so we remove that too.
Most of pci-hotplug.c was additionaly protected by #ifdef TARGET_I386. The
small piece which wasn't is only called from the pci_add and pci_del hooks
in hmp-commands.hx, which themselves were protected by #ifdef TARGET_I386.
This patch therefore also removes the #ifdef from pci-hotplug-old.c,
and changes the ifdefs in hmp-commands.hx to use CONFIG_PCI_HOTPLUG_OLD.

Avoid use of static variables: PC systems
initialize pvpanic device through pvpanic_init,
so we can simply create the fw_cfg file at that point.
This also makes it possible to skip device
creation completely if fw_cfg is not there, e.g. for xen -
so the ports it reserves are not discoverable by guests.
Also, make pvpanic_init void since callers ignore return

Coverity complains about two overruns in process_tx_desc(). The
complaints are false positives, but we might as well eliminate
them. The problem is that "hdr" is defined as an unsigned int,
but then used to offset an array of size 65536, and another of
size 256 bytes. hdr will actually never be greater than 255
though, as it's assigned only once and to the value of
tp->hdr_len, which is an uint8_t. This patch simply gets rid of
hdr, replacing it with tp->hdr_len, which makes it consistent

kvmclock should not count while vm is paused, because:
1) if the vm is paused for long periods, timekeeping
math can overflow while converting the (large) clocksource

2) Users rely on CLOCK_MONOTONIC to count run time, that is,
time which OS has been in a runnable state (see CLOCK_BOOTTIME).
Change kvmclock driver so as to save clock value when vm transitions
from runnable to stopped state, and to restore clock value from stopped

Mac OS X's debugging serial driver accesses the ESCC through a different
register layout, called "escc-legacy". This layout differs from the normal
escc register layout purely by the location of the respective registers.
This patch adds a memory alias region that takes normal escc registers and
maps them into the escc-legacy register space.
With this patch applied, a Mac OS X guest successfully emits debug output
on the serial port when run with debug parameters set, for example by running:

RTAS is a hypervisor provided binary blob that a guest loads and
calls into to execute certain functions. It's similar to the
vsyscall page in Linux or the short lived VMCI paravirt interface
from VMware.
The QEMU implementation of the RTAS blob is simply a passthrough
that proxies all RTAS calls to the hypervisor via an hypercall.
While we pass a CPU argument for hypercall handling in QEMU, we
don't pass it for RTAS calls. Since some RTAs calls require
making hypercalls (normally RTAS is implemented as guest code) we
have nasty hacks to allow that.
Add a CPU argument to RTAS call handling so we can more easily
invoke hypercalls just as guest code would.

Graf (along with some other improvements).
Note from Alex regarding kvm_irqchip_create():
On x86, one would call kvm_irqchip_create() to initialize an
in-kernel interrupt controller. That function then goes ahead and
initializes global capability variables as well as the default irq
routing table.
On ppc, we can't call kvm_irqchip_create() because we can have
different types of interrupt controllers. So we want to do all the
things that function would do for us in the in-kernel device init

The "info mtree" command in QEMU console prints only "memory" and "I/O"
address spaces while there are actually a lot more other AddressSpace
structs created by PCI and VIO devices. Those devices do not normally
have names and therefore not present in "info mtree" output.
The patch fixes this.

Now, everywhere we have a DMAContext we also have access to the

the DMAContext, or because dma_context_memory's AddressSpace is
trivially address_space_memory).

So far, the size of all regions passed to listeners could fit in 64 bits,
because artificial regions (containers and aliases) are eliminated by
the memory core, leaving only device regions which have reasonable sizes
An IOMMU however cannot be eliminated by the memory core, and may have
an artificial size, hence we may need 65 bits to represent its size.

Option -no-fd-bootchk asks the BIOS to attempt booting from a floppy
even when the boot sector signature isn't there, by setting a bit in
RTC CMOS. It was added back in 2006 (commit 52ca8d6a).
Two years later, commit 0ecdffbb added monitor command boot_set.
Implemented by new function pc_boot_set(). It unconditionally clears
the floppy signature bit in CMOS.
Commit e0f084bf added -boot option once to automatically change the
boot order on first reset. Reuses pc_boot_set(), thus also clears the
floppy signature bit. Commit d9346e81 took care to preserve this
behavior.
Thus, -no-fd-bootchk applies to any number of boots. Except it
applies just to the first boot with -boot once, and never after
boot_set. Weird. Make it stick instead: set the bit according to
-no-fd-bootchk in pc_boot_set().

When this VMSD was introduced it's version fields were set to
sizeof(I6300State), making them essentially random from build to build,
version to version.
To fix this, we lock in a high version id and low minimum version id to
support old->new migration from all prior versions of this device's
state. This should work since the device state has not changed since
its introduction.
The potentially breaks migration from 1.5+ to 1.5, but since the
versioning was essentially random prior to this patch, new->old
migration was not consistently functional to begin with.

Issuing the READ CAPACITY(10) command in the guest will cause QEMU
to update its knowledge of the maximum accessible LBA in the disk.
The recorded maximum LBA will be wrong if the disk is bigger than
1TB, because ldl_be_p returns a signed int.
When this is fixed, a latent bug will be unmasked. If the READ
CAPACITY(10) command reported an overflow (0xFFFFFFFF), we must
not overwrite the previously-known maximum accessible LBA, or the guest
will fail to access the disk above the first 2TB.

Tray statuses should be also reset. Some guests may lock the tray and
right after resetting the guest it should be unlocked and closed. This
is done on power-on, reset and resume from suspend/hibernate on bare-metal.
This fix is already committed for IDE CD.
Check the commit a7f3d65b65.
Test results on bare-metal:
- on reset/power-on the CD-ROM tray is closed even before the monitor
is turned on
- on resume from suspend/hibernate the tray is also closed before
the monitor is turned on
From test results it seems that this behavior is OS and probably BIOS
independent.

This is a little strange. It is lowering the parent IRQ pin on input

Acking a level sensitive interrupt should have no effect if the
interrupt pin is still asserted. The current implementation requires
and edge condition to occur for setting a level sensitive IRQ, which
means an ACK can clear a level sensitive interrupt, until the original
source strobes the interrupt again.
Fix by keeping track of the interrupt pin state and setting ISR based
on this every time update_irq() is called.
