Change fw_cfg_add_file() to get full file path as a parameter instead
of building one internally. Two reasons for that. First caller may need
to know how file is named. Second this moves policy of file naming out
from fw_cfg. Platform may want to use more then two levels of
directories for instance.

This includes that the timer is stopped which is especially important
if the guest does a reboot independantly of a watchdog bite. I moved

The e1000 has compatibility code to handle big endianness which makes it
mandatory to be recompiled on different targets.

With the generic mmio endianness solution, there's no need for that anymore.
We just declare all mmio to be little endian and call it a day.

move the driver over to Makefile.objs.

The only reason we have bswap versions of the pci host code is that
most pci host devices are little endian. The ppc e500 is the only
odd one here, being big endian.

So let's directly pass the endianness down to the mmio layer and not
worry about it on the pci host layer.

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.

This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

The way we're currently modeling mmio is too simplified. We assume that
every device has the same endianness as the target CPU. In reality,
most devices are little endian (all PCI and ISA ones I'm aware of). Some
are big endian (special system devices) and a very little fraction is
target native endian (fw_cfg).

So instead of assuming every device to be native endianness, let's move
to a model where the device tells us which endianness it's in.

That way we can compile the devices only once and get rid of all the ugly
swap will be done by the underlying layer.

For the same of readability, this patch only introduces the helper framework
but doesn't allow the registering code to set its endianness yet.

This patch adds more printf format checking.

Additional modifications were needed for this code change:

* alpha-dis.c: The local definition of MAX conflicts with
  a previous definition from osdep.h, so add an #undef.

* dis-asm.h: Add include for fprintf_function (qemu-common.h).
  The standard (now redundant) includes are removed.

* mis-dis.c: The definition of ARRAY_SIZE is no longer needed
  and must be removed (conflict with previous definition from
  qemu-common.h).

* sh4-dis.c: Remove some unneeded forward declarations.
