/*****************************************************************************

This is a decoder for RTCM-104 3.x, a serial protocol used for
broadcasting pseudorange corrections from differential-GPS reference
stations.  The applicable specification is RTCM 10403.1: RTCM Paper
177-2006-SC104-STD.  This obsolesces the esrlier RTCM-104 2.x
specifications. The specification document is proprietary; ordering 
instructions are accessible from <http://www.rtcm.org/>
under "Publications".  

Unike the RTCM 2.x protocol, RTCM3.x does not use the strange
sliding-bit-window IS-GPS-200 protocol as a transport layer, but is a
self-contained byte-oriented packet protocol.  Packet recognition is
handled in the GPSD packet-getter state machine; this code is
concerned with unpacking the packets into well-behaved C structures,
coping with odd field lengths and fields that may overlap byte
boudaries.  These report structures live in gps.h.

Note that the unpacking this module does is probably useful only for
RTCM reporting and diagnostic tools.  It is not necessary when
passing RTCM corrections to a GPS, which normally should just be
passed an entire correction packet for processing by their internal
firmware.
