Modified PJ structure to hold a_orig, es_orig, ellipsoid definition before
adjustment for spherical projections.
Modified pj_datum_transform() to use the original ellipsoid parameters,
not the ones adjusted for spherical projections.
Modified pj_datum_transform() to not attempt any datum shift via
geocentric coordinates if the source *or* destination are raw ellipsoids
(ie. PJD_UNKNOWN). All per PROJ bug #1602, GDAL bug #2025.
