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.

2019-02-01erts: Remove dead ERTS_MAGIC_REF_BIF_TIMERS codeLukas Larsson
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.

2019-01-21Optimize the is_function/2 guard testBjörn Gustavsson
The is_function2 instruction is executed surprisingly frequently when running dialyzer or the compiler. It cannot hurt to optimize it a little.
2019-01-18erts: Use reduction based polling for starved poll-setLukas Larsson
When the schedulers never go to sleep (and thus never polls) it may be that the fds in schedulers poll-sets are never polled. Before this commit, this was solved by starting a timer when an overload was detected. This had issues as overloads were not always detected in time. So this commit reverts to the pre OTP-21 behaviour so keep a global counter makes that the poll is called when it should.

There seems to be an incorrect merge conflict resolution in abde22933f5a that merged maint to master. Dumping of references (and possibly other terms) were broken.
