cobalt/kernel: Introduce __SCHED_CURRENT policy to setschedparam_ex

Define the internal scheduling policy "current": it shall refer to the
target thread's current scheduling policy. This will allow to model
pthread_setschedprio on top of pthread_setschedparam_ex with only a
single syscall.

[Xenomai-git] Jan Kiszka : lib/cobalt: Wrap pthread_setschedprio for proper real-time support

lib/cobalt: Wrap pthread_setschedprio for proper real-time support

Implement pthread_setschedprio on top of pthread_setschedparam_ex with
the help of the new __SCHED_CURRENT policy. This ensures that prio
changes are directly applied to the real-time core, and that with just
a single syscall.
