Fix returned error from gen_tcp:accept/1,2 when running out of ports
The {error, enfile} return value is badly misleading and confusing for this case, since the Posix ENFILE errno value has a well-defined meaning that has nothing to do with Erlang ports. The fix changes the return value to {error, system_limit}, which is consistent with e.g. various file(3) functions. inet:format_error/1 has also been updated to support system_limit in the same manner as file:format_error/1.
