Changeset 2529 for LMDZ5

Message:

Reviewing the way swaero_diag is computed to correct an old bug that
makes topswad and co diagnostics wrong for the first timestep...
And introducing swaero_diag in rrtm/recmwf_aero so that double and
triple radiation calls when diagnostics are not needed to save time
