Thomas Gleixner 5d916a0988 posix-timers: Add a refcount to struct k_itimer ...

To cure the SIG_IGN handling for posix interval timers, the preallocated
sigqueue needs to be embedded into struct k_itimer to prevent life time
races of all sorts.

To make that work correctly it needs reference counting so that timer
deletion does not free the timer prematuraly when there is a signal queued
or delivered concurrently.

Add a rcuref to the posix timer part.
