Revision 173

correctbid did nothing. (Not used either in LMDZ since revision 1170.)

Avoid aliasing in arguments of nat2gcm: use a single set of arguments
with intent inout. Argument q of nat2gcm was not used.

pres2lev now accepts po in any monotonic order. So the input files for
nudging can now have the pressure coordinate in any order. Also, we
read the latitude coordinate from the input files for nudging and we
invert order if necessary so the input files for nudging can now have
the latitude coordinate in any order.

In pre2lev, no need for lmomx: use automatic arrays.

Removed variable ncep of module conf_guide_m. Instead, we find out
what the pressure coordinate is with find_coord.
