iothread: replace fair_mutex with a condition variable

This conveys the intention better, and scales to more than >1
threads contending the mutex with the iothread (as long as all
of them have a "quiescent point" like the TCG thread has).

Also, on Mac OS X the fair_mutex somehow didn't work as intended
and deadlocked.
