Sticky Tag:

fix ldd97 slope limit ; clean-up time-average.

o some bug fixes for #undef REAL4_IS_SLOW

 o convert all comments with single quotes (such as "can't", "don't", etc.)
     to unabbreviated form (eg. "do not") since these unmatched quotes
     tend to break the Fortran parser used to generate the HTML-ified
     code browser (see: http://mitgcm.org/dev_docs/code_reference/)

Yet more changes:
o adgmredi_calc_tensor
  avoiding all recomputation of gmredi_slope_limit
o adgmredi_x/y/rtransport
  added flag for excessive storing to avoid recomp. of
  u/v/rtans, dTdx/y/z
  -> this is not really necessary and very memory-consuming
o adgmredi_slope_psi:
  consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
o gmredi_slope_limit
  re-activated full calculation of taperfct for case 'ac02'

add GM_Small_Number & GM_slopeSqCutoff (replace Large_SlopeSqr)
 as running-time parameter (data.gmredi)
 default value are 1.d-12 & 1.d+48 resp.
GM_EXCLUDE_() replace GM_TAPER_() in gmredi_slope_limit.F

fix few bugs and restore parameter value (e.g., Small_Number=1.D-12)
and scheme (e.g., Large_SlopeSqr=1.D+48) of checkpoint47f_post

o few modif.'s to get latest version adjointed
  (mainly kick out code in ini_linear_phisurf)
o modif's to run adjoint with exactConserv
o case GM_BOLUS_ADVEC should be cleaned
  S/R gmredi_slope_psi should be cleaned
o verification/carbon now has exactConserv=.TRUE.

Here they are, before they get changed/lost/stolen.
Mostly modif.'s to fix numerical sensitivities.
Gradient checks OK for
- GM_taper_scheme:
  * clipping
  * ac02
  * linear
  * glw91
  * dm95
  * ldd97
- GMREDI_OPTIONS:
  * GM_VISBECK_VARIABLE_K
  * GM_NON_UNITY_DIAGONAL
  * GM_EXTRA_DIAGONAL
  * GM_BOLUS_ADVEC
in conjunction with data.gmredi parameters to be checked in
in a few minutes under verification/carbon/code/

o * "clean" adjoint code (in terms of extensive recomputations)
    can now be obtained for all GMREDI options (i.e. for
    - GM_VISBECK_VARIABLE_K
    - GM_NON_UNITY_DIAGONAL
    - GM_EXTRA_DIAGONAL
    - GM_BOLUS_ADVEC )
  * However, wrong gradient check problem remains unsolved.
  * New CPP options have been introduced for different
    tapering schemes

Made sure each .F and .h file had
the CVS keywords Header and Name at its start.
Most had header but very few currently have Name, so
lots of changes!
