Instead of calling the IOAPIC from the PIC, raise IOAPIC irqs via the ISA bus.
As a side effect, IOAPIC lines 16-23 are enabled.

This reverts commit 8217606e6e (and
updates later added users of qemu_register_reset), we solved the
problem it originally addressed less invasively.

The parameter is always zero except when registering the three internal
io regions (ROM, unassigned, notdirty). Remove the parameter to reduce
the API's power, thus facilitating future change.

Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.
Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.

Subject: [PATCH] Split ioapic logic from the current apic.
Add a new ioapic.c to hold ioapic's logic, and also
make it work for ia64.
