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.

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.

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.

common_test requires that if init_per_suite/1 exists, then
end_per_suite/1 must also exist. If end_per_suite/1 does not exist,
then it will be marked in the log as failed with reason 'undef'. Some
test suites are corrected to avoid this.

6209607916799026
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.

For the benefit of Travis CI, include more test cases from
otp_SUITE in the smoke test. That will avoid having to run
a pull request through the daily builds to find those kind
of minor issues.

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()
