Thread parking for Kotlin/Common

[bbrockbernd]

Allows to pause and resume thread execution. On native platforms it is based on pthread_cond_wait, on JVM it uses LockSupport.

Threads can be pre unparked (calling unpark before park cancels the parking operation). And thread can be parker with a timeout.

Suspend the current thread by calling:

Parker.park()

Resume a thread by calling:

Parker.unpark(thread)

Get current thread reference by calling:

val thread = KThread.currentThread()

Parking with timout of 500 nano seconds:

Parker.parkNanos(500)
