Changes since 1.5: +2 -2 lines 
merged from ecco-branch:
o exf:
  - Enable initialisation of forcing fields to constant
    (runtime) values.
  - in exf_getffields.F
    Reduce i-/j-loop to interior domain, discarding overlaps.
    That also fixes wrong TAF-key computations for key_1, key_2
    with bulf formulae.
  - exf_init.F modify #ifdef for exf_init_evap
  - exf_getffieldrec.F, ctrl_getrec.F
    The following INT-usages are not safe:
      fldsecs  = int(fldsecs/fldperiod)*fldperiod
      fldcount = int(fldsecs/fldperiod) + 1
    and were modified.
