Also move check of non-atom states in callback mode
state_functions to where the state function is called.
This gives homogenous diagnostics for state functions,
code_change/4 and system_replace_state StateFun.
Irregularities pointed out by James Fish.

Removing events from the internal queues is not necessary with
the choosen semantics of the event queue vs. hibernate.
In an early implementation it was possible by combining
hibernate with e.g. postpone to get an event in the queue
that you would not see before processing the postponed event,
and therefore should you decide to cancel a timer it was
essential to be able to remove that unseen event from the queue.
With the choosen semantics you will have to postpone or generate
an event for it to be in the event queue, and if you e.g. postpone
a timeout event and then cancel the timer it is your mistake.
You have seen the event and should know better than to try to
cancel the timer.
So, the actions: remove_event, cancel_timer, demonitor and unlink
are now removed.
There have also been some cleanup of the timer handling code.

Correct typo reported by Luïc Hoguin.

StateName/4 -> StateName/3
handle_event/5 -> handle_event/4

Define options as actions that set options,
rework the documentation about this.

Cleanup some error handling

OTP-13290
|

Speed up supervisor:count_children/1 for simple_one_for_one
supervisors. This is achieved by avoiding looping through all the
child process and verifying that each one is alive.
For a supervisor with 100,000 'temporary' children the count-time will
drop from approx 25ms to about 0.005ms.
For a supervisor with 100,000 'permanent' or 'transient' children the
count-time will drop from approx 30ms to about 0.005ms.
This avoids having the supervisor block for an extended period while
the count takes place. Under normal circumstances the accuracy of the
result should also improve since the duration is too short for many
processes to die during the count.
