erts: Change erl_exit into erts_exit

This is mostly a pure refactoring.

Except for the buggy cases when calling erlang:halt() with a positive
integer in the range -(INT_MIN+2) to -INT_MIN that got confused with
ERTS_ABORT_EXIT, ERTS_DUMP_EXIT and ERTS_INTR_EXIT.

Outcome             OLD erl_exit(n, )         NEW erts_exit(n, )
-------             -------------------       -------------------------------------------
exit(Status)        n = -Status <= 0          n = Status >= 0
crashdump+abort     n > 0, ignore n           n = ERTS_ERROR_EXIT < 0

The outcome of the old ERTS_ABORT_EXIT, ERTS_INTR_EXIT and
ERTS_DUMP_EXIT are the same as before (even though their values have
changed).
