ae4b76c8d3 New interrupt code. The basic idea behind it is to hide the differences 
in interrupt controllers in struct pic, and try to keep as much
common code as possible. At the lowest (asm) level, this is done
with CPP macros.

The main structure is now struct intrsource, describing an established
interrupt line, of any kind (soft/hard local apic/legacy apic/IO apic).
For quick masking, there may be a maximum of 32 sources per CPU.
Sources can be assigned to any CPU in the MP case, though currently they
all go to the boot CPU.

26ab868e68 Merge Bill Sommerfeld's i386 MP branch. This code has some known 
caveats, but works quite well in a lot of MP cases, and all
UP cases that I have tested. Parts of this will hopefully be
reworked in the not-too-distant future.

e207174eb0 Add functions to read EISA configuration data for MEM, IRQ, DMA, and IO. 
XXX Just error stubs on the i386 right now -- someone needs to write
XXX EISA BIOS code for i386.

b84a8f42d9 Implement eisa_mem_{alloc,free}(), a method for allocating/freeing 
EISA bus physical address space.

cd9ef2be9c make the EISA code look a bit more like the PCI code, in the way 
the bus is configured, interrupts are handled, etc.  define
eisa_chipset_tag_t and eisa_intr_handle_t types, and the following
functions:
        eisa_attach_hook()
        eisa_maxslots()
        eisa_intr_map()
        eisa_intr_string()
        eisa_intr_establish()
        eisa_intr_disestablish()
to do the right things for the i386.

fedca4f133 Attach isa, eisa, and pci to mainbus now, rather than root. The i386 
now has a single device tree (rather than a forest).  Also, attach
EISA only if it's present, and attach in order: PCI, EISA, ISA (most
specific to least specific).
