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....

Revert "xen: start PCI hole at 0xe0000000 (same as pc_init1 and qemu-xen-traditional)"

This reverts commit 9f24a8030a70ea4954b5b8c48f606012f086f65f.

The start of the PCI hole is actually set to 0xf0000000 by hvmloader.
In order to retain ABI compatibility with Xen we leave the start of the...
