Description
Current implementation of the pressure gradient... blablabla... We modify the implementation of the pressure gradient according to A19 from NEMO book 4.0.1 : in dynhpg routines we compute the specific pressure gradient with the density anomaly : when possible we merely remove the znad, otherwise we remove explicitely the surface pressure gradient (dynhpg_prj, dynhpg_djc). in dynspg routines we compute the surface pressure gradient with constant density systematically
Note that using a density anomaly only in dynhpg_isf, requires also changes in isfload and isfstp.

Because we change the arrangement of adding and subtractig the "surface pressure gradient" we do not expect to have the same results as before.
