  Support GDAL 2.0 64bit integer fields

Now that http://trac.osgeo.org/gdal/wiki/rfc31_ogr_64 has been
committed in GDAL trunk 2.0dev, OFTInteger64 can be return as a
field type.
So :
- when reading OGR layer, support mapping OFTInteger64 to a new "Long" datatype
- when reading PostGIS layer, map INT8 columns to "Long" datatype
- in mapwfs, map "Long" to xs:long
- in OGR output code, map "Long" to OFTInteger64, if GDAL 2.0, or
  OFTReal otherwise

OGR_F_GetFID() in GDAL 2.0 returns a 64 bit integer. We just fix
warnings by casting to int, but if a 64bit FID was really returned,
we might have issues.
