Split scsh code into lots of modules.
...
Note that this change doesn't represent any sort of design suggestion
or decision: It merely represents an attempt to codify the
dependencies between the parts of the code base. There's still lots
of work to be done to actually make user-accessible modules.

I did it again:

only multiply timeout by 1000 if it's a number.

It had to happen: the first post-0.6.3 bug fix.
...
The SELECT* operations take a timeout argument, specified to be in
seconds. Instead, they took milliseconds. Fix this.

Change SELECT! in the same way as SELECT: only ask the buffers of

ports that were passed in, not those of raw file descriptors.

Change the semantics of select so that it doesn't check the underlying

Revamped the SELECT implementation to properly distinguish between
...
input and output port. Also, SELECT and SELECT! are no longer
squashed into one silly procedure.

Convert optional timeout argument before calling wait-for-channels.

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.

Make FLUSH-ALL-PORTS blocking so FORK will do something more sensible.
...
Previously,
(begin
(display "ha!") (newline)
(fork (lambda ()
'foo)))
would print "ha!" twice because FLUSH-ALL-PORTS would not finish
before the actual FORK.
