s3-param Use .offset rather than .ptr when defining parameters

s3-param Use .offset rather than .ptr when defining parameters

This change has a number of purposes:

 * It removes the fancy logic around pointers into sDefault for all
   per-share parameters.  Instead, this is always expressed as an
   offset, rather than implicitly via PTR_DIFF macros.

 * It makes struct parm_struct almost identical to that as used in
   source4/param.  This will very shortly allow the loadparm tables
   and most of the 'special' helper functions to be placed in common.
