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]).
