Glibc's posix timer testcase found a lot of bugs in posix timer code.
This series, hopefully, fixes all of them. All patches are independent
each other logically.
Changes from v4
- [1/8] comments colarification, fix account_group_{user_system}_time too.
- [8/8] added CPUCLOCK_VIRT and CPUCLOCK_PROF timer initialization fix
Changes from v3
- task_sched_runtime() micro optimization add to care tsk->on_cpu.
suggested Paul Turner.
- fixed several typo in changelogs.

posix-cpu-timers: fix acounting delta_exec twice
posix-cpu-timers: fix wrong timer initialization
posix-cpu-timers: timer functions should use timer time instead of
clock time
posix-cpu-timers: check_thread_timers() uses task_sched_runtime()
sched: task_sched_runtime introduce micro optimization
posix-cpu-timers: cleanup cpu_{clock,timer}_sample{,_group}
