Before commit 63ffb564, states for
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
the logic completely to pc.c, which caused a regression.

Fix by adding the same check also to pc.c.

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".

[ v2: add copyright to files                     ]
[ v2: use qemu-common.h for standard includes    ]
[ v2: create separate qxl-vga device for primary ]

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
spec.

Allow the intercept the RTC IRQ for the HPET legacy mode. Then push
routing to IRQ8 completely into the HPET. This allows to turn
hpet_in_legacy_mode() into a private function. Furthermore, this stops
the RTC from clearing IRQ8 even if the HPET is in control.

This patch comes with a side effect: The RTC timers will no longer be
stoppend when there is no IRQ consumer, possibly causing a minor
performance degration. But as the guest may want to redirect the RTC to
the SCI in that mode, it should normally disable unused IRQ source
anyway.
