Al Viro 99e6c0e6ec posix-timers: Store rmtp into restart_block in sys_clock_nanosleep()
... instead of doing that in every ->nsleep() instance

Thomas Gleixner f2c45807d3 alarmtimer: Switch over to generic set/get/rearm routine
All required callbacks are in place. Switch the alarm timer based posix
interval timer callbacks to the common implementation and remove the
incorrect private implementation.

Thomas Gleixner 525b8ed916 posix-timers: Add cancel/arm callbacks
Add timer_try_to_cancel() and timer_arm() callbacks to kclock which allow
to make common_timer_set() usable by both hrtimer and alarmtimer based
clocks.

Thomas Gleixner 63841b2a69 posix-timers: Add forward/remaining callbacks
Add two callbacks to kclock which allow using common_)timer_get() for both
hrtimer and alarm timer based clocks.

Thomas Gleixner f37fb0aa4f posix-timers: Use timer_rearm() callback in posixtimer_rearm()
Use the new timer_rearm() callback to replace the conditional hardcoded
calls into the hrtimer and cpu timer code.

This allows later to bring the same logic to alarmtimers.

Thomas Gleixner 3080294589 posix-timers: Add timer_rearm() callback
Add a timer_rearm() callback which is used to make the rescheduling of
posix interval timers independent of the underlying clock implementation.

Thomas Gleixner bab0aae9dc posix-timers: Move posix-timer internals to core
None of these declarations is required outside of kernel/time. Move them to
an internal header.
