[PATCH FOR REVIEW] rc.subr: use stderr instead of stdout for trap handlers

Hash: SHA256

Hi,

Currently if certain signals is received, rc.subr's trap instruction
would inject output to standard output.  This could be a problem if
the script uses standard output for other purposes, e.g. generating a
configuration file, etc.

The proposed change redirects these information to standard error.

Objections?

Cheers,
