Rename the rc binary to openrc

Debian requested this rename due to the "rc" binary conflicting with the
"rc" binary from the plan 9 shell.

We also add a deprecation warning to the binary when it is run as rc to
encourage users to switch to openrc instead.

 been removed. If you need these scripts, look for a package called
 netifrc, which is maintained by them.
 
+As of OpenRC-0.13, the /sbin/rc binary has been renamed /sbin/openrc.
+There is a /sbin/rc symbolic link in place currently in case you are
+still using the old name.  However, it is strongly advised that you
