  threads are no longer suspended during startup

- so Thread.getThis will always be set in the signal handler

  Changed paths:
    M src/core/thread.d

  Log Message:
  -----------
  suspend threads in parallel

- heavily reduce suspendAll time with many threads by signalling all N
  threads in parallel and then waiting N times for the semaphore rather
  than doing that serially
- won't improve anything on OSX/Windows which do use a synchronous
  suspend API

- move critical region handling into suspend method
- change FreeBSD's m_suspendagain workaround to a per thread flag
