Update to 2.96.

* Mon Mar 21 2011 Eric S. Raymond <esr@snark.thyrsus.com> - 2.96~dev
  Bumped maximum channel count to 32 to accommodate GPS+GLONASS devices.
  API version bumped to 5, redesign finished (changes are documented
  in the Client HOWTO). cgps now handles resize signals. Code can now
  link with uClibc for embedded use.  Various bugs in the C++ binding
  have been fixed. gpxlogger can now daemonize and write to a specified
  log file. A gpsd client can now set any locale it likes, and JSON
  will still be parsed using the C locale matching the daemon's.  Clients
  are no longer required to define a gpsd_report() hook. gpsd no longer
  emits probe strings to unidentified USB devices at startup.
  JSON timestamps in TPV and SKY are now ISO8601 rather than seconds since
  the Unix epoch; the library handles the older style backward-compatibly.
  GPGST sentences are now parsed for noise statistics when a device emits them.
  AIS and RTCM2 JSON dumps have device fields. JSON reports now include 50bps
  subframe data if the device allows access to it. gpsdecode can now dump NMEA
  GPS binary, and subframe data to JSON. The RTCM2 code now understands and
  analyzes RTCM2.3 messages 13, 14, and 31, and has been checked against another
  analyzer.  The ancient Sager dump format for RTCM2 is abolished in favor of
  a JSON profile.
