  Real-time thread priority was been forbidden on Unix
because of problems they can cause.
Warnings and helpers are added to avoid deadlocks,
so real-time can be allowed on all systems.

Thomas Monjalon (2):
  eal: add thread yield functions
  eal/unix: allow creating thread with real-time priority

v1: no yield at all
v2: more comments, sched_yield() and Sleep(0) on Windows
v3: 2 yield functions with sleep in realtime version
v4: runtime warning, longer sleep on Unix and lighter yield on Windows
v5: fix build and increase Unix sleep to 1 ms

  eal/unix: allow creating thread with real-time priority
