Removed unused variables pks, pk, pkf from main program unit gcm.

Encapsulated procedures exner_hyb, exner_hyb_p, exner_hyb_loc,
exner_milieu, exner_milieu_p and exner_milieu_loc into
modules. (Compulsory to allow optional arguments.)

In the procedures exner_hyb, exner_hyb_p, exner_hyb_loc, donwgraded
arguments alpha and beta to local variables. In exner_milieu,
exner_milieu_p and exner_milieu_loc, removed beta altogether. In the
six procedures exner_*, made pkf an optional argument. Made some
cosmetic modifications in order to keep the six procedures exner_* as
close as possible.

In the six procedures exner_*, removed the averaging of pks at the
poles: this is not useful because ps is already the same at all
longitudes at the poles. This modification changes the results of the
program. Motivation: had to do this for exner_hyb because we call it
from test_disvert with a few surface pressure values.

In all the procedures calling exner_*, removed the variables alpha and
beta. Also removed variables alpha and beta from module leapfrog_mod
and from module call_calfis_mod.

Removed actual argument pkf in call to exner_hyb* and exner_milieu*
from guide_interp, guide_main, iniacademic and iniacademic_loc (pkf
was not used in those procedures).

Argument workvar of startget_dyn is used only if varname is tpot or

  1. When varname is tpot or q, the actual argument associated to

workvar in etat0_netcdf is not y. So y in etat0_netcdf is a
place-holder, never used. So we remove optional argument y in the
calls to exner_hyb and exner_milieu from etat0_netcdf.

Created procedure test_disvert, called only by etat0_netcdf. This
procedure tests the order of pressure values at half-levels and full
levels.
