Video streaming detection heuristics in spice-server have problems
keeping modern desktop animations (as done by gnome shell) and real
video playback apart. This leads to jpeg compression artefacts on
your desktop, due to spice using mjpeg to send what it thinks is
a video stream.
Turn off video detection by default to avoid these artifacts.

Every address space has its own nodes and sections, but
it uses the same global arrays of nodes/section.
This limits the number of devices that can be attached
to the guest to 20-30 devices. It happens because:
- The sections array is limited to 2^12 entries.
- The main memory has at least 100 sections.
- Each device address space is actually an alias to
main memory, multiplying its number of nodes/sections.
Remove the limitation by using separate arrays of
nodes and sections for each address space.

Owning to some different hardware design, piix and q35 need
different compat. So making them diverge.
On q35, IRQ2/8 can be reserved for hpet timer 0/1. And pin 16~23
can be assigned to hpet as guest chooses. So we introduce intcap
property to do that.
Consider the compat and piix/q35, we finally have the following
value for intcap: For piix, hpet's intcap is hard coded as IRQ2.
For pc-q35-1.7 and earlier, we use IRQ2 for compat reason. Otherwise
IRQ2, IRQ8, and IRQ16~23 are allowed.

According to hpet spec, hpet irq is high active. But according to
ICH spec, there is inversion before the input of ioapic. So the OS
will expect low active on this IRQ line. (On bare metal, if OS driver
claims high active on this line, spurious irq is generated)
We fold the emulation of this inversion inside the hpet logic.

qemu uses "pci" as name for pci bridges in the firmware device path.
seabios expects "pci-bridge". Result is that bootorder is broken for
devices behind pci bridges.
Some googling suggests that "pci-bridge" is the correct one. At least
PPC-based Apple machines are using this. See question "How do I boot
from a device attached to a PCI card" here:
http://www.netbsd.org/ports/macppc/faq.html
So lets change qemu to use "pci-bridge" too.

We previously allocated 32-bits per temp for the next_free_temp entry.
We now allocate 4 bits per temp across the 4 bitmaps.
Using a linked list meant that if a translator is tweeked, resulting in
temps being freed in a different order, that would have follow-on effects
throughout the TB. Always allocating the lowest free temp means that
follow-on effects are minimized, which can make it easier to diff output
when debugging the translators.
