sgabios hasn't gotten a lot of coverage since it was not shipped. For 1.0,
let's disable the automatic loading of the option ROM in -nographic
mode. We can put it back for 1.1.

apic id returned to guest kernel in ebx for cpuid(function=1) depends on
CPUX86State->cpuid_apic_id which gets populated after the cpuid information
is cached in the host kernel. This results in broken CPU topology in guest.
Fix this by setting cpuid_apic_id before cpuid information is passed to
the host kernel. This is done by moving the setting of cpuid_apic_id
to cpu_x86_init() where it will work for both KVM as well as TCG modes.

Commit 63ffb564 broke floppy devices specified on the command line like
-drive file=...,if=none,id=floppy -global isa-fdc.driveA=floppy because it
relies on drive_get() which works only with -fda/-drive if=floppy.
This patch resembles what we're already doing for IDE, i.e. remember the floppy
device that was created and use that to extract the BlockDriverStates where
needed.

The master PIC is connected to the LINTIN0 of the APICs. As the APIC
currently does not track the state of that line, we have to ask the PIC
to reinject its IRQ after the CPU picked up an event from the APIC.
This introduces pic_get_output to read the master PIC IRQ line state
without changing it. The APIC uses this function to decide if a PIC IRQ
should be reinjected on apic_update_irq. This reflects better how the
real hardware works.
The patch fixes some failures of the kvm unit tests apic and eventinj by
allowing to enable the proper CPU IRQ deassertion when the guest masks
some pending IRQs at PIC level.

This is based on the original fix by Hervé Poussineau: pc_memory_init
actually takes a memory region for mapping BIOS and extension ROMs. That
equals the PCI memory region if PCI is available, but must be system
memory in the ISA case.

The current implementation of PAM and the PCI holes is broken in several
ways:
- PCI BARs are not restricted to the PCI hole (a BAR may hide memory)
- PCI devices do not respect PAM (if a PCI device maps a region while
PAM maps the region to RAM, the request will be honored)
This patch fixes things by introducing a pci address space, and using
memory region aliases to represent PAM regions, SMRAM, and PCI holes.
The memory hierarchy looks something like
system_memory
|
+--- low memory alias (0-0xe0000000)
| |
| +-- ram@0
|
+--- high memory alias (0x100000000-EOM)
| |
| +-- ram@0xe0000000
|
+--- pci hole alias (end of low memory-0x100000000)
| |
| +-- pci@end-of-low-memory
|
|
+--- pam[n] (0xc0000-0xc3fff etc) (when set to pci, priority 1)
| |
| +-- pci@0xc4000 etc
|
+--- smram (0xa0000-0xbffff) (when set to pci/vga, priority 1)
|
+-- pci@0xa0000 etc
ram (simple ram region)
pci
|
+--- BARn
|
+--- VGA 0xa0000-0xbffff
|
+--- ROMs

We've always listened on port 501 for vgabios panic messages. In the entire
time I've worked on QEMU, I've never actually seen a vgabios panic message :-)
If we change the semantics of this port a little bit, it makes it possible to
use it for more interesting use-cases. I chose this approach instead of adding
a new I/O port because it avoids having a guest visible change.
This change allows single-byte access to port 501 and also uses the value
written to construct an exit code.

This patch adds a dummy legacy ISA device whose responsibility is to
deploy sgabios, an option rom for a serial graphics adapter.
The proposal is that this device is always-on when -nographics,
but can otherwise be enable in any setup when -device sga is used.

floppy drives were calculated in fdc.c:fd_revalidate(). There it is
also considered whether a disk is inserted or not. The commit didn't copy

qxl is a paravirtual graphics card. The qxl device is the bridge
between the guest and the spice server (aka libspice-server). The
spice server will send the rendering commands to the spice client, which
will actually render them.
The spice server is also able to render locally, which is done in case
the guest wants read something from video memory. Local rendering is
also used to support display over vnc and sdl.
qxl is activated using "-vga qxl". qxl supports multihead, additional
cards can be added via '-device qxl".

Drives defined with -drive if=ide get get created along with the IDE
controller, inside machine->init(). That's before cmos_init().
Drives defined with -device get created during generic device init.
That's after cmos_init(). Because of that, CMOS has no information on
them (type, geometry, translation). Older versions of Windows such as
XP reportedly choke on that.
Split off the part of CMOS initialization that needs to know about
-device devices, and turn it into a reset handler, so it runs after
device creation.

Currently HPET ACPI table is created regardless of whether qemu actually
created hpet device. This may confuse some guests that don't check that
hpet is functional before using it. Solve this by passing info about
hpets in qemu to seabios via fw config interface. Additional benefit is
that seabios no longer uses hard coded hpet configuration. Proposed
interface supports up to 8 hpets. This is the number defined by hpet
