2019-02-22erts: Implement fragmentation of distrubution messagesLukas Larsson
2019-02-21erts: Move reason in dist messages to payloadLukas Larsson
The dist messages EXIT, EXIT2 and MONITOR_DOWN have been updated with new versions that send the reason term as part of the payload of the message instead of as part of the control message. This allows the decode of the reason to be done by the receiving process instead of the dist entry which in turn makes it possible for multiple decodes to be done in parallel. This change is done in order to make it easier to fragment the potentially large payload of EXIT, EXIT2 and MONITOR_DOWN into multiple distribution messages. OTP-15611
2019-02-21erts: Remove a copy of distribution data payloadLukas Larsson
Before this change the inet driver was in list mode and thus the data from it had to be copied when received by the dist entry. This change puts the tcp port in binary mode and makes the any refc binary created by it be used all the way to the process where it is decoded. Thus eliminating one copy of the entire message payload.

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.

2019-02-01[socket-nif] nosup expection of win32 and type(s) replacementsMicael Karlberg
The nif callback functions (nif_open) now instead cause an 'nosup' exception if called (instead of badarg). The basic type uint16_t, uint32_t and int32_t (C99) replaced "own" (that is, defined by "us") types Uint16, Uint32 and Sint32. The point of this is that our Windows build system seems to be a bit lacking when it comes to types... Removed "some stuff" that was if-defed. Different solution when win32 support for sockets has been improved. Make sure the socket_*.c util modules are not included in the building for windows. OTP-15526
