  Three entities:

  synctask - glusterfs implementation of xlator friendly lightweight threads
  Coroutine - qemu coroutine API for its block drivers
  CoroutineSynctask - implementation of Coroutine using synctasks

  Coroutine is an "embedded" structure inside CoroutineSynctask, called "base".

  E.g:

  Coroutine *co;
  CoroutineSynctask *cs;
  struct synctask *synctask;

  cs == synctask->opaque;
  co == &(cs->base);
  cs = DO_UPCAST(CoroutineSynctask, base, co);
  synctask == cs->synctask;
