SMS status report

From: Erin Yueh <erin_yueh@openmoko.com>
Subject: [PATCH] SMS status report

I made a patch for SMS status report. It can change SMS-Submit messages
and ask for a status report. When  the destination address receives our
message, the service center will send a SMS-STATUS-REPORT to us. We can
tell what messages we sent by TP-MR (message reference number) value and
can know the sending result by TP-ST (Status) value from status report
messages.
