Coordinate transformation: improve transformations from/to WGS84 (Gxxxx)
Currently very few transformations from/to WGS84 (Gxxxx) are registered
in the EPSG database, and there isn't even transformations between WGS84 EPSG:4326
and those ones. Consequently transformations to those realizations often
ended up as no-operation, whereas going through WGS84 EPSG:4326 will bring
more meaningful results. So register those EPSG:4326<-->WGS 84 (Gxxx)
null transformations, and when having WGS 84 (Gxxx) as source/target,
consider EPSG:4326 as an intermediate.
This change has no effect on the existing direct transformations
from/to WGS 84 (Gxxx).
