This patch tackles all files that are compiled once, moving
them to subdirectories of hw/.

pci_bridge_dev_map_irq_fn() is identical to pci_swizzle_map_irq_fn(),
which is now the default for all PCI bridges.  We can therefore remove
this function and the pci_bridge_map_irq() call that used it.

Done with this script:

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.

Since 39bffca2 (qdev: register all
types natively through QEMU Object Model), TypeInfo as used in
the common, non-iterative pattern is no longer amended with information
and should therefore be const.

Fix the documented QOM examples:

 sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h

Since frequently the wrong examples are being copied by contributors of
new devices, fix all types in the tree:

 sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c
 sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c

This also avoids to piggy-back these changes onto real functional
changes or other refactorings.

There are lots of external users of pci_internals.h,
apparently making it an internal interface only didn't
work out. Let's stop pretending it's an internal header.

update all users so we can remove the makefile hack.

Not a single driver has any possibility of failure on their
exit function, let's keep it that way.

Currently, we do not properly cleanup, if pci_bridge_dev_initfn
fails to initialize properly. Make sure to call pci_bridge_exitfn()
in the error path.

There is no point in pushing this burden to the devices, they tend to
forget to call them (like intel-hda, ahci, xhci did). Instead, reset
functions are now called from pci_device_reset. They do nothing if
MSI/MSI-X is not in use.

This adds support for a standard pci to pci bridge,
enabling support for more than 32 PCI devices in the system.
Device hotplug is supported by means of SHPC controller.
For guests with an SHPC driver, this allows robust hotplug
and even hotplug of nested bridges, up to 31 devices
per bridge.
