✘gpsd 3.20 is released!

[Gary E. Miller]

Happy New Year!

Almost.  At least where I sit.  Just under the wire gpsd 3.20 is
released.

6 months in the making.  1067 commits.  27 authors.

Let us hold off on major changes for a bit in case a 3.20.1 is
required.  Doc and small changes always welcome.

Changes this release:

3.20: 2019-12-31
  Change README into an asciidoc file and publish HTML from it
  Add NED and geoid_sep to gps_fix_t and TPV JSON.
  Add "-e NED" to ubxtool to enable NED messages.
  gpsdata.separation replaced by gpsdata.fix.geoid_sep.
  Remove nofloats build option.
  TPV JSON "alt" is now fixed at WGS84.  Probably.
  xgps now uses XGPSOPTS environment variable.
  add health variable to satellite_t
  change satellite_t elevation and azimuth to double
  satellite_t elevation, azimuth, and ss use NAN for unknown value.
  add altMSL, altHAE, and depth, to gps_fix_t
  altitude in gps_fix_t is deprecated and undefined
  wgs84_separation() now return EGM2008 computed from 5x5 degree base data.
     The best results are close to cm, the worst off up to 12m.
  Move mag_var from gps_device_t to magnetic_var gps_data_t.
  Added mag_var() to interpolate magnetic variation (deviation) from a table.
  Remove true2magnetic() as mag_var() improves on it.
  Remove TIMEHINT_ENABLE.  It only worked when enabled.
  Remove NTP_ENABLE and NTPSHM_ENABLE.  It only worked when enabled.
  Remove PPS_ENABLE and TIMING_ENABLE.
  Add dgps_age and dgps_station to gps_fix_t
  Convert all timestamp_t to timespec_t.
  Remove FIXED_PORT_SPEED and FIXED_STOP_BITS build options.
  Add -s [speed] and -f [framing] runtime options to gpsd.
  A working CC and termios.h are mandatory.
