Remove all traces of nad2bin and nad2nad

The source material for the default grids used by
PROJ has been moved to the proj-datumgrid repository. For that
reason it is no longer necessary to include the nad2bin program
in the PROJ repository and source distribution. From now on the
nad2bin application will be kept in the proj-datumgrid repo.

Previously the null grid was generated by running nad2bin on the
null.lla file. Since nad2bin is no longer available null.lla has
been replaced by its binary counterpart null. This file will be
distributed and installed alongside PROJ.

Build scripts and documenation has been adjusted so that nad2bin
is not mentioned anywhere. Additionally all references to nad2nad
has been removed as well. nad2nad has not been part of the PROJ
distribution for quite some time so this has been long overdue.
