Now, in child specification, the shutdown value can also be set to infinity
for worker children. This restriction was removed because this is not always
possible to predict the shutdown time for a worker. This is highly
application-dependent.

According to the supervisor's documentation:
"Important note on simple-one-for-one supervisors: The dynamically
created child processes of a simple-one-for-one supervisor are not
explicitly killed, regardless of shutdown strategy, but are expected
to terminate when the supervisor does (that is, when an exit signal
from the parent process is received)."
All is fine as long as we stop simple_one_for_one supervisor manually.
Dynamic children catch the exit signal from the supervisor and leave.
But, if this happens when we stop an application, after the top
supervisor has stopped, the application master kills all remaining
processes associated to this application. So, dynamic children that trap
exit signals can be killed during their cleanup (here we mean inside
terminate/2). This is unpredictable and highly time-dependent.
In this commit, supervisor module is patched to explicitly terminate
dynamic children accordingly to the shutdown strategy.
NOTE: Order in which dynamic children are stopped is not defined. In
fact, this is "almost" done at the same time.

In the current implementation of supervisors, temporary children
should never be restarted. However, when a temporary child is
restarted as part of a one_for_all or rest_for_one strategy where
the failing process is not the temporary child, the supervisor
still tries to restart it.
Because the supervisor doesn't keep some of the MFA information
of temporary children, this causes the supervisor to hit its
restart limit and crash.
This patch fixes the behaviour by inserting a clause in
terminate_children/2-3 (private function) that will omit temporary
children when building a list of killed processes, to avoid having
the supervisor trying to restart them again.
Only supervisors in need of restarting children used the list, so
the change should be of no impact for the functions that called
terminate_children/2-3 only to kill all children.
The documentation has been modified to make this behaviour
more explicit.

supervisor:terminate_child/2 was not allowed if the supervisor used
restart strategy simple_one_for_one. This is now changed so that
children of this type of supervisors can be terminated by specifying
the child's Pid.

This change fixes a bunch of small (and a few less small) typos and
other errors in various modules that I've spotted throughout my travels.

Avoid seed values that are even divisors of the primes
and by that prevent getting seeds that are stuck on zero.
Example: random:seed(0,0,0) would produce a series of only zeros.
