Move the v3 resource allocator to v2.

Major changes:
1. Separate resource allocation into:
	A. Read Resources
	B. Avoid fixed resources (constrain limits)
	C. Allocate resources
	D. Set resources

Usage notes:
Resources which have IORESOURCE_FIXED set in the flags constrain the placement
of other resources.  All fixed resources will end up outside (above or below) 
the allocated resources.

Domains usually start with base = 0 and limit = 2^address_bits - 1.

I've added an IOAPIC to all platforms so that the old limit of 0xfec00000 is
still there for resources.  Some platforms may want to change that, but I didn't
want to break anyone's board.

Resources are allocated in a single block for memory and another for I/O.
Currently the resource allocator doesn't support holes.
