Add simple implementation for two raster operations that are used by
AmigaOS which fixes graphics problems in some programs using these.

Pixman may return false if it does not have a suitable implementation.
Add fallbacks to handle such cases.

Add a property to allow disabling pixman and always use the fallbacks
for different operations which is useful for testing different drawing
methods or debugging pixman related issues.

From: BALATON Zoltan <balaton@eik.bme.hu>
According to the PegasosII schematics the PCI interrupt lines are
connected to both the gpp pins of the Mv64361 north bridge and the
PINT pins of the VT8231 south bridge so guests can get interrupts from
either of these. So far we only had the MV64361 connections which
worked for on board devices but for additional PCI devices (such as
network or sound card added with -device) guest OSes expect interrupt
from the ISA IRQ 9 where the firmware routes these PCI interrupts in
VT8231 ISA bridge. After the previous patches we can now model this
and also remove the board specific connection from mv64361. Also
configure routing of these lines when using Virtual Open Firmware to
match board firmware for guests that expect this.
This fixes PCI interrupts on pegasos2 under Linux, MorphOS and AmigaOS.

Add basic implementation of the AC'97 sound part used in VIA south
bridge chips. Not all features of the device is emulated, only one
playback channel is supported for now but this is enough to get sound
output from some guests using this device on pegasos2.
