2017-11-20erts: Remove erts_internal:maps_to_list/2Lukas Larsson
This function is no longer needed as maps:iterator has now been implemented.
2017-11-20erts: Implement batching maps:iteratorLukas Larsson
This iterator implementation fetches multiple elements to iterate over in one call to erts_internal:maps_next instead of one at a time. This means that the memory usage will go up for the iterator as we are buffering elements, but the usage is still bounded. In this implementation the max memory usage is 1000 words. Using this approach makes the iterator as fast as using maps:to_list, so maps:iterator/2 has been removed.
2017-11-17Avoid using the efile driver in test suitesBjörn Gustavsson
The efile driver will soon be reimplemented as a BIF. Instead of opening a port based on efile, use hd(erlang:ports()). It is a reasonable safe assumption that the runtime will continue to use use at least some ports.

2017-11-15erts: Put pending DistrEntry in separate listSverker Eriksson
2017-11-15Refactor auto_connect into an outline functionSverker Eriksson
and abort_pending_connection into own utility function.

2017-11-15erts: Keep magic ref to DistEntry in net_kernelSverker Eriksson
to make sure it's kept alive.
2017-11-15Allow DistEntries in ETSSverker Eriksson
2017-11-15Remove faulty assertSverker Eriksson
Send may have failed, port exit with dist_entry cleaned up and then new pending connection with queued messages.
2017-11-15erts: Transcode tuple fallbacksSverker Eriksson
When finalizing outgoing distribution messages we transcode them into using tuple fallbacks if the receiver does not support bitstrings and export-funs. This can only happen if the message was first encoded toward a pending connection when the receiver was unknown. It's an optimistic approach optmimized for modern beam nodes, that expect real bitstrings and funs (since <R13). Only erl_interface/jinterface lack this support.
2017-11-15erts: Ensure enc_term_int() always do progressSverker Eriksson
even when reds <= 1 Removed micro optimization for first fun variable to make things simpler.
2017-11-15Add optimistic DFLAG_DIST_HOPEFULLY for pending connectionsSverker Eriksson
to avoid tuple fallbacks for export funs and bitstrings. ToDo: Re-encode if receiver turn out to be erl_interface/jinterface.
2017-11-15erts: Fix auto-connect toward erl_interface/jinterfaceSverker Eriksson
2017-11-15erts: Let send(_,_,[noconnect]) enqueue msg on pending connection.Sverker Eriksson
The least bad behavior I think: * We cannot return 'noconnect' as caller might already have enqueued monitor/link that never triggers. * We cannot block waiting for connection as that can ruin latency when 'noconnect' is used to avoid blocking auto-connect (see gen_server and gen_statem). But there might be users getting more cases of bad latency waiting for a pendig connection, instead of a fast 'noconnect'.

2017-11-15erts: Async auto-connect for monitor_nodeSverker Eriksson
Removed distribution_SUITE:applied_monitor_node as it seems to test apply of trapping BIF and monitor_node does not trap anymore.
2017-11-15erts: Introduce asynchronous auto-connectSverker Eriksson
2017-11-15erts: Refactor connection_id in ErtsDistExternalSverker Eriksson
Break out from 'flags' into new dedicated 'connection_id' just for simplicity. Also changed flags to low bits and that affected enif_binary_to_term.
2017-11-15erts: Make DFLAGS_NEW_FUN_TAGS mandatorySverker Eriksson
and remove ugly encoding fallback as {fun, ...} DFLAGS_NEW_FUN_TAGS has been supported by vm/erl_interface/jinterface since R13 or even older. Renamed test case obsolete_funs to term2bin_tuple_fallbacks and removed test for {fun,...} fallback and added missing test for bitstring fallback {Binary, Bits}.

2017-11-15erts TEST: Add missing ref to DistEntry from send contextSverker Eriksson
2017-11-15erts: Fix bug in DistEntry refc danceSverker Eriksson
to handle "lookup without refc++" correctly which was introduced in 4dcb2ae7810a507b701a30072b2f514cab7ebbdb. When decrementing refc to zero (in try_delete or prepare_try_delete) we must always wait thread progress to make sure no thread has done lookup without refc++ and is just about to do refc++ and thereby revive the DistEntry. That is, we wait for a potential other thread to either do refc++ or drop its pointer to the DistEntry. And if that other thread does refc++ (in erts_ref_dist_entry) it must also do the extra refc++ for the scheduled pending delete.
