Without this fix asserts would trigger in debug build
but nothing else would break.

We walk through all signal queues in the system when clearing
seq_trace, so we must be prepared to encounter all kinds of
signals.

* max-au/erts/dirty_scheduler_shutdown/PR-2172/OTP-15690:
erts: release dirty runqueue lock before entering endless loop when BEAM is shutting down
# Conflicts:
# erts/emulator/beam/erl_process.c

shutting down
This patch fixes a problem happening when BEAM is shutting down. It is possible for a dirty scheduler to take the lock, and keep it, when the system is shutting down. It may also happen that a normal scheduler decides to schedule some dirty job (example is major garbage collection that results in migrating the process into dirty CPU queue), and hangs trying to take the lock that will never be released.
To fix the problem, either release the lock before entering endless wait loop, or reverse the order in which schedulers are stopped. Either fix works, and, of course, it works even better to apply both.

If a suspend/resume signal pair was sent to a process while it
was executing dirty the resume counter on the process got into
an inconsistent state. This in turn could cause the process
to enter a suspended state indefinitely.

Many heap fragments do no longer make the GC slow.
Even worse, we are not guaranteed that a yield will provoke a GC
removing the fragments, which might lead to a one-yield-per-bucket
scenario if the heap fragment(s) still remains after each yield.

Instead rely on gnu make's pre-defined RM variable which should

The idea here is that the timeout of 0 will work like a yield
so that that we don't starve other ports/processes, but it
is faster than the select trigger. We don't deselect on the socket
because it does not matter if it is triggered laster or not
as we'll just get an EAGAIN.
Doing this also circumvents the fact that no select is done on
active true style sockets until all I/O has been handled. So in
a system with a lot of active true style I/O this will could be
very benificial.

This is most likely a copy-paste bug that has lived in the code
unnoticed for 5+ years...

We only want to autoupdate update the buffer if recbuf
is set if the buffer has not been set before.

Symptom:
Heart kills exiting emulator before is has flushed all ports
and with HEART_KILL_SIGNAL=SIGABRT it may also produce
unnecessary core dumps from doing init:reboot() for example.
Problem:
Heart port is closed together with all the others in handle_reap_ports()
which is detected by heart OS process.
Solution 1:
Leave the heart port alone in handle_reap_ports() and let it be closed
by OS when emulator exists. It doesn't need to be flushed anyway.
Solution 2:
When heart OS process gets EOF on connection let it wait max 5 seconds
for emulator process to self terminate before trying to kill it.

Using magic refs for big timers caused too large a stress on
the off_heap GC implementation to be viable, so it was never
enable. The code is now broken because of other changes to
we might as well remove it.

"shift count negative or too big, undefined behavior"

The bug could be seen by running the test that is added by this commit
in a valgrind enabled emulator.
