When a client behind a NAT issues a pause command, and stay paused for a
long time, the router may stop the RTP/RTCP port redirection. Resend the
hole punching packets before each PLAY command to cause the router to
restart the port redirection in that case.

Move the existing code for sending the packets from the SETUP phase
to the PLAY phase.

Since not all systems need the libraw1394 dependency, let pkg-config
provide the list of libraries actually needed.

The libdc1394-2.pc file has been included since version 2 (2008-01-05),
so it should be safe to use.
