Added support for svdrpservice plugin (Thanks to Frank Schmirler).

Added INFO SVDRP command (partially based on patch by Herbert Pötzl).
Removed system log option - use SVDRP instead.
Added --remove-destination to the 'cp' command in Makefile.

+Client-server architecture:
+
+The SVDRP service extension can be used in client-server configurations.
+A streamdev based VDR-to-VDR streaming client can retrieve frontend
+information from a server, if the SVDRP service has been activated and
+properly configured in femon. The svdrpservice plugin is required on the
+VDR client.
+
+If the client fails to open a DVB card frontend corresponding to the
+current receiving device, it will connect to the SVDRP server, look for
+the femon plugin and tune the channel on the server to the one currently
+viewed on the client. If one of these steps fails, the femon OSD won't
+open on the client. An SVDRP icon in the femon title bar indicates that
+the data source is SVDRP. The device number in the title bar is always
+the local device number.
