2019-07-01erts: Fix integer overflow in list subtractionJohn Högberg
CMP_TERM returned an `Sint`, which overflowed the `int` used in erl_rbtree for storing the comparison, causing list subtraction to behave strangely.

2019-03-07erts: Remove ets traversal yielding if heap fragmentSverker Eriksson
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.

2019-02-18erts: Add yield via timeout to inet read_packetLukas Larsson
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.
2019-02-18erts: Don't increase buffer when sctp sndbuf is setLukas Larsson
This is most likely a copy-paste bug that has lived in the code unnoticed for 5+ years...
2019-02-18erts: Only change inet buffer if not setLukas Larsson
We only want to autoupdate update the buffer if recbuf is set if the buffer has not been set before.

2019-02-14erts: Avoid heart killing a nicely exiting emulatorSverker Eriksson
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.
