commit 62c96360
    virtio-pci: fix level interrupts
only helps systems without irqfd: on systems with irqfd support we
passed in flag requesting irqfd even when msix is disabled.

As a result, for level interrupts we didn't install an fd handler so
unmasking an fd had no effect.

Fix this up.

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

non-irqfd setups are currently broken with vhost:
we start up masked and nothing unmasks the interrupts.
Fix by using mask notifiers, same as the irqfd path.

Sharing irqchip/non irqchip code is always a good thing,
in this case it will help non irqchip benefit
from backend masking optimization.

All PCI nics are switched to EFI-enabled roms by default.  They are
composed from three images (legacy, efi ia32 & efi x86), so classic
pxe booting will continue to work.

Exception: eepro100 is not switched, it uses a single rom for all
emulated eepro100 variants, then goes patch the rom header on the
fly with the correct PCI IDs.  I doubt that will work as-is with
the efi roms.

Keep old roms for 1.4+older machine types via compat properties,
needed because the efi-enabled roms are larger so the pci rom bar
size would change.

cd hw
for i in `find . -name '*.h' | sed 's/^..//'`; do
  echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,'
done | sed -i -f - `find . -type f`

This is so that paths remain valid as files are moved.

Instead, files in hw/dataplane are referenced with the relative path.
We know they are not going to move to include/, and they are the only
include files that are in subdirectories _and_ move.
