  3. Expand arguments in the default platform_probe! 

    This prevents a warning that was seen in the examples on wasm.

  5. The semaphore is enabled by any non-zero value 

    The semaphore value is incremented by each attached tool, so we should
check if it's non-zero, not just exactly 1.

  6. Put semaphores in static mut 

    This is mainly so they're not placed in read-only memory. Most debugging
tools can poke RO memory anyway, but SystemTap puts its semaphores in
the RW `.probes` section.
