Update init.d scripts to handle stderr; readd splash screen for remote consoles

When r376428 was commited to re-order start up sequences to be more tolerant of
forking with thread primitives, a few items were changed that caused changes
in behavior on some distros. This includes:
 * Not displaying the splash screen on a remote console.
 * Displaying an error message on stderr when a remote console cannot connect
   to a running instance of Asterisk.

In the first case, the splash screen was re-added (thanks to Michael L. Young).
In the second case, the various init.d scripts were modified to pipe stderr
to /dev/null, as the error message is useful - if you execute a remote
console or a remote console command execution and it fail, it should tell
you. Note that the error message was always present, it just failed to be
printed prior to r376428.

Much thanks to the folks who quickly reported this problem, provided solutions,
and promptly tested the various init.d scripts on a variety of distros.

 ===========================================================
+
+from 1.8.20.0 to 1.8.20.1:
+* Asterisk would previously not output certain error messages when a remote
+  console attempted to connect to Asterisk and no instance of Asterisk was
+  running. This error message is displayed on stderr; as a result, some
+  initialization scripts that used remote consoles to test for the presence
+  of a running Asterisk instance started to display erroneous error messages.
+  The init.d scripts and the safe_asterisk have been updated in the contrib
+  folder to account for this.
+
 from 1.8.19 to 1.8.20:
 * Asterisk has always had code to ignore dash '-' characters that are not
   part of a character set in the dialplan extensions.  The code now
