fsemaphore cleanup
...
- abstract over JIT inlining of fsemaphore operations
- fix problems with non-parallel fsemaphores
- adjust tests so they don't assume too much concurrency
- clarify fsemaphore vs. semaphore in the docs

Fix fsemaphore-try-wait? so the sema's count is decremented. Make fsemaphore-wait and other futures-related functions cooperate with the GC better.

fix `touch' to run a suspended future in the runtime thread
...
if no future thread is running the future; also adjust the
policy for suspending a future so that even synchronized
operations can suspend if there's other work to be done;
also also fix `current-future' for nested `touch'es and when
parallel futures are disabled

adjust futures to decouple blocked futures from worker threads
...
which required adding a notion of "lightweight continuation" to
the runtime system, where a lightweight continuation involves
only frames from JIT0generated code (so that details of the stack
layout are known, for example)

current-future now returns #f if not inside a future, instead of null. Added documentation for current-future.

Added (current-future) to the futures module (as an inlined, nonblocking primitive).

fix a GC problem related to future and wcm; also fix a race condition related to JITing a delay-loaded procedure (and maybe specific to future-demanded JITting)
