vm: interrupt stdin_loop when entering fep
...
The stdin_loop thread will keep trying to consume input unless we stop it by sending it a signal. Use SIGUSR2 to stop the read syscall and a mutex to hold up the loop while the fep is active.

vm: enqueue signals for FEP signals too
...
Although SIGINT still can't interrupt the current Factor thread in a sane way, this will at least wake up the run loop when waiting for input and fix #348 when implemented at the application level.

vm: switch atomic::add to atomic::fetch_add
...
Win32 only provides fetch-and-add, not add-and-fetch, and we don't really care. Rename the functions so the order of operations is clear.
