the IO-APIC.
* Merge r41758 from trunk as well, but with disabled panics in the fallback
cases. It is needed to complete the routing when the IO-APIC is enabled.
This also prevents the IO-APIC from being used if the routing can't be fully
established. With the disabled panics it will simply print the reason and fall
back to PIC mode.

Add the ACPI module (and the DPC dependency) to the floppy boot image. It is
used for el-torito booting the CD and anyboot images. Due to the previous lack
of the ACPI module on these, IO-APICs wouldn't get enabled on CD or anyboot
images booted via CD drives.

* set up a dumb deframer.
* received isochronous buffers can be zero length: loop instead of breaking.

* convert determine_haiku_revision to only contain functions and now pass the arguments
via function call

pin configuration as the configuration only happens after preparing the
configuration where we already need the NMI mask.

the macros. This makes things more readable and also fixes the few remaining
80 char limit violations. No functional change intended.

* Use that function from ioapic_configure_io_interrupt() and use it when
configuring NMI sources to actually set the entries to NMI.

unavailable for routing so that we don't end up configuring anything on them.
I haven't seen these in actual use though.

we use a 64 bit level triggered mask. In practice these don't exist as far as I
know. If we encounter them at a later stage we need to revisit the mask.

at the override entry to trigger the overriden vector so that we don't need
to configure any additional redirections.
* Also configures the polarity and trigger modes found in the override entry.
* When disabling the legacy PIC, retrieve the enabled interrupts and re-enable
then in the IO-APIC. This will for example make the ACPI SCI work that is
installed prior to switching interrupt models. Through the transparent support
for interrupt source overrides it'll also automatically relay from the old to
the new vector.
This should make ACPI interrupts work and should support relocating the ISA PIT
from irq 0 to a different global system interrupt (usually 2) so that it can
still work when IO-APICs are in use.

all reports so far have been positive. We fall back to legacy mode in the cases
where we can't figure out the correct routing.

* remove device_type and replace with device_chipset
* change MEMSIZE to >> 10 as r600-r700 store this in bytes (r800 uses MB and will be fixed soon)
* add if statement to select what register locations to use based on chipset
** Maybe use a struct or something to store these in a standardized way?
