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.

* sverker/prealloc-race-bug/OTP-14491:
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 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.

Problem: Adding/subtracting 0.5 and large double floats between
(1 bsl 52) and (1 bsl 53) does not give reliable results.
Solution: Use round() function in math.h.

Atomic reference count of binaries also in non-SMP
Conflicts:

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()
