USE_POINT_Z_M usability

Hi All,

I guess the usability of the USE_POINT_Z_M option is quite limited
right now, and none of the binary distributions are distributed with
this setting enabled.

In my opinion mapserver should work using the 3D data sources as well
without having to recompile the source for this particular data type.

Moreover as looking into the code most of the additional activity is
limited only to retrieve the additional elements into the additional
fields of the shapeObj-s.

There have also been some memory corruption problems with some of the
SWIG bindings when mapscript and mapserver were compiled with
different USE_POINT_Z_M settings and the size of the shapeObj
structure was different accordingly.

Shouldn't we instead get rid of this option and treat every shapes as
2D shapes (or 3D shapes if we want)?

Best regards,
