We can't just leave it in queue with dist_ext=NULL.
Two symptoms seen:
1. 'receive' trying to deref dist_ext as NULL.
2. GC think it's a term and put THE_NON_VALUE in root set.

Symptom: VM crash when erlang:trace_pattern(on_load, ..) is set and
module with -on_load is loaded.
Problem: Tracing and -on_load clash in their use of Export.beam[1]
Solution: Do not do call set_default_trace_pattern in finish_loading_1
for modules with -on_load. finish_after_on_load_2 will do that anyway.

erts: Fix bug in quick alloc
|

Wrong result for
(X bsl WS) bxor Y.
where
X is any negative integer
Y is any integer that does not require more words than X
WS is erlang:system_info(wordsize) or larger
Fix: The subtraction of 1 (for 2-complement conversion)
must be carried along all the way to the last words.

The effect of the race is that a pre-allocated memory block
is inserted last without updating tail.data.last, which will cause
all subsequent insertions to also fail to update tail.data.last.
Hence all pre-allocation for this quick alloc instance is leaked
for this thread and will fallback on erts_alloc.

Before this fix, the extra data attached to a port task had to
be cleaned up by the calling function. This caused problems
because the outputv call, co-allocates the extra data with the
port task. So in rare circumstances the port task would be
free'd before the extra data was free'd which led to segfault
when looking at the port task.
This has been fixed by the generic PORT_TASK_ABORT behaviour
being used even for tasks dropped in the erts_schedule_proc2port_signal
API.

The socket left lingering due to {exit_on_close, false} will accept writes
in a confusing way, returning either enotconn or blocking. This fix allows
socket to know that it has been closed recently, and new writes won't pass.

This fixes a bug where a send/shutdown error on an active-mode socket results
in the port never being properly closed.

This is a stopgap measure before the release of OTP-20 where
that makes it possible for the user to make the vm not do
anything with SIGTERM and instead rely on the OS default.
To enable this behaviour the user should set the environment
variable ERL_ZZ_SIGTERM_KILL="true".

The signal handler will now schedule a sigterm message instead of sending
the message in the signal handler. The signal handler must refrain from
memory allocations and thus the event is scheduled.

fix for already merged but not releases 808b2f4d53e446aed07f85716c5c4b85abb3d18a

def_arg_reg[0] is used for storage of timeout instruction
when a 'receive after' is executed. When a process was
scheduled out inside prim_eval:'receive'/0 due to a function
call, def_arg_reg[0] was overwritten due to storage of live
registers.
prim_eval:'receive'/2 now calls arg_reg_alloc/0 which
bumps all reductions and then calls arg_reg_alloc/7
which will cause an allocation of a new arg_reg array
since def_arg_reg only can hold 6 values. This ensures
that the timeout instruction in def_arg_reg[0] used
for the timeout wont be overwritten.
