Axe the barrier_{read,write,rw}() helper functions as this method of
...
doing memory barriers doesn't really scale well for the ia64. Also,
memory barriers are more a property of the CPU than bus space.

Add in a simple API for memory barriers to machine/bus.h:
...
- barrier_read() enforces a memory read barrier
- barrier_write() enforces a memory write barrier
- barrier_rw() enforces a memory read/write barrier

This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will
...
not work on any real hardware (or fully work on any simulator). Much more
needs to happen before this is actually functional but its nice to see
the FreeBSD copyright message appear in the ia64 simulator.
