Update history of SHAPELIB copy:

* files shpopen.c,shapefil.h,dbfopen.c:
   from ogr/ogrsf_frmts/shape/
* file safileio.c
   from SHAPELIB itself (http://download.osgeo.org/shapelib/)

Last update
* taken from GDAL 2.1.2 and SHAPELIB 1.3.0 (Thu Nov 24 10:45:41 CET 2016)
* taken from GDAL 1.5.1-SVN (Sun Mar 30 11:20:43 CEST 2008)
* taken from GDAL 1.5.0-CVS (Wed Sep  5 13:48:48 CEST 2007)
* taken from GDAL 1.3.2-CVS (Sat Jun 17 22:08:04 CEST 2006)

Additional fixes:
* dbfopen.c
   around line 1270: GDAL bug #809 (http://trac.osgeo.org/gdal/ticket/809)
   remove CPLsnprintf
   remove CPL_IGNORE_RET_VAL_INT
   for WIN32, define snprintf as in shpopen.c

* shpopen.c
  define CPL_UNUSED

* safileio.c
  SHP_CVSID: ISO C does not allow extra ‘;’ outside of a function

* Use <grass/shapefil.h> etc rather than "shapefil.h"
   in shpopen.c, dbfopen.c, and safileio.c
