Cosmetic fix: the file uses explicit STRUCTURE-REFs for all
...
references to THREADS-INTERNAL except one. Make that one reference
into a STRUCTURE-REF also.

Redo the forking-without-the-threads fix in a way not involving
...
command levels (as there *are* no command levels for things like scsh
-c):
There's now a new asynchronous event, similar to SPAWN, called NARROW.
It spawns off a new scheduler with just one thread (which runs the
thunk provided as an argument to NARROW) and blocks the current one
until the narrowed scheduler finishes.
For this to work, two schedulers need to be in place: the root
scheduler which performs the housekeeping, and another one inside that
which is the one the program uses---otherwise it's the root scheduler
that's blocked, and that means no housekeeping gets done. This is
trivially the case for interactive mode, as the command-levels all
have their own schedulers, but we also need to make sure scsh's entry
point fires up its own initial scheduler.

interrupt/alarm is now generated by itimer in low-interupt. command-level set no longer a handler for interrupt/keyboard. sighandler now generates the event for Interrupt: keyboard

made os-signal base of the interrupt system.
...
There is now a enumeration scsh-os-signal, that lists all signals. The function set-interrupt now acts on scsh-os-signal-handlers-vector, not any longer on the vm-vector.
The with-enabled-interrupts etc stuff does NOT work at the moment.

Added files from david fishers home (~dfisher/scsh-0.5.1).

Be warned: the scsh-version he started from was neither 0.5.1 nor
0.5.2, but something in between !
