pc_sysfw: do not make it a device anymore

Move the code to hw/i386, the sole remaining property is available
as !pci_enabled.

pc: limit 64 bit hole to 2G by default

It turns out that some 32 bit windows guests crash
if 64 bit PCI hole size is >2G.
Limit it to 2G for piix and q35 by default.
User may override default 64-bit PCI hole size by
using "pci-hole64-size" property.

Examples:...

target-i386: Disable PMU CPUID leaf by default

Bug description: QEMU currently gets all bits from GET_SUPPORTED_CPUID
for CPUID leaf 0xA and passes them directly to the guest. This makes
the guest ABI depend on host kernel and host CPU capabilities, and
breaks live migration if we migrate between hosts with different...

virtio-net: add feature bit for any header s/g

Old qemu versions required that 1st s/g entry is the header.

Since QEMU 1.5, patchset titled "virtio-net: iovec handling cleanup"
removed this limitation but a feature bit is needed so guests know it's
safe to lay out header differently....

vmport: Disentangle read handler type from portio

In case the latter may vanish one day, make sure the vmport read handler
type will remain unaffected. This is also conceptually cleaner.

pvpanic: initialization cleanup

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 -...

pc: pass PCI hole ranges to Guests

Guest currently has to jump through lots of hoops to guess the PCI hole
ranges. It's fragile, and makes us change BIOS each time we add a new
chipset. Let's report the window in a ROM file, to make BIOS do exactly
what QEMU intends....
