sperber 33c14d7901 First stab at implementing SELECT/SELECT!:
- extend the VM interrupts to distinguish between read and write
  events
- add new ADD-PENDING-CHANNEL instruction to the VM
- add WAIT-FOR-CHANNELS procedure to the run-time system
- implement SELECT and SELECT! on top of that in newports.scm

This runs some basic tests, but in general should be considered
largely untested.

Moreover, SELECT/SELECT! never detect any exceptional conditions---the
returned vectors are always empty.  This is because the VM doesn't
really track those, and it's unclear whether it would be worth the
effort.
