The special creation of 0 is used by internally created externals,
such as when list_to_pid is called. This creation should compare
equal to all externals creations of that external. If it does not
we can end up in very strange scenarios. For instance:
> P = spawn(OtherNode, fun() -> die end).
<8303.60.0>
> link(<8303.60.0>).
true
> flush().

The reason in EXIT and DOWN may be arbitrarily large,
so we yield and allow other processes to execute while
encoding and sending the signals over the distribution.
|

|

This commit removed the general send context (which was used
very little anyways) and only uses the distributed send context.
This will make it easier to use the dist API at the cost of
a little bit more code for the local send.

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.

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.

All of the Red-Black Tree _yielding functions have been
updated to work with reductions returned by the called
function instead of yielding on each element.

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.
