New routines

  iau_EFORM     a,f for a nominated Earth reference ellipsoid
  iau_GC2GD     geocentric to geodetic for a nominated ellipsoid
  iau_GC2GDE    geocentric to geodetic given ellipsoid a,f
  iau_GD2GC     geodetic to geocentric for a nominated ellipsoid
  iau_GD2GCE    geodetic to geocentric given ellipsoid a,f

Miscellaneous

  Where appropriate, Julian and Besselian epochs such as J2000
  and B1900 have had the conventional ".0" added.  About one
  third of the routines were affected by this cosmetic change.
