Support arbitrary crash report in proc_lib.
The `error_logger_format_depth` variable is `unlimited` by default. This can cause errors when logging crash reports using sasl logger, because `io_lib:format("~P"...` does not support `unlimited` as a depth parameter. Use formatter string "~p" for unlimited depth. A way to reproduce the error: Start erl with sasl logger: erl -boot start_sasl -sasl errlog_type error -sasl sasl_error_logger tty Report arbitrary error: error_logger:error_report(crash_report, [fake_crash_report, foo]).
