2017-11-23erts: Fix erlang:monitor toward c-nodesSverker Eriksson
by suppressing DOP_MONITOR_P, DOP_MONITOR_P_EXIT and DOP_DEMONITOR_P if not supported by the remote node. In 17e198d6ee60f7dec9abfed272cf4226aea44535 I changed the behavior of erlang:monitor to not raise badarg for c-nodes but instead create a monitor to only supervise the connection. But I forgot to prevent DOP_MONITOR_P and friends from being sent to the node that does not expect them. Note: We test both DFLAG_DIST_MONITOR and DFLAG_DIST_MONITOR_NAME for the node to support process monitoring. This is because erl_interface is buggy as it sets DFLAG_DIST_MONITOR without really supporting it. ToDo: Should erl_interface stop setting DFLAG_DIST_MONITOR or should we change the meaning of these flags?
2017-11-21erts: Fix preemption bug in erts_dist_commandSverker Eriksson
We should break out when out of reductions.

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.
2017-11-15Remove 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.
2017-11-15Add 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.

2017-02-06Atomic reference count of binaries also in non-SMPRickard Green
NIF resources was not handled in a thread-safe manner in the runtime system without SMP support. As a consequence of this fix, the following driver functions are now thread-safe also in the runtime system without SMP support: - driver_free_binary() - driver_realloc_binary() - driver_binary_get_refc() - driver_binary_inc_refc() - driver_binary_dec_refc()
