Fix build of dxf2shp plugin with GDAL 2.2 

Up to know the plugin relied on the fact that GDAL exported the symbols of
its internal shapelib. Since GDAL 2.2 this is no longer the case. So build
the internal copy of shapelib in the plugin, but to avoid symbol name clashes,
prefix the shapelib symbols with qgis_. And also use GDAL VSI large API for I/O
so that on Windows on particular non ASCII filenames are properly handled.
