I must have missed that "The ownership of the returned geometry belongs to
the caller."

In contrast, with OGR_G_ForceTo() "a new [geometry is] returned (or
potentially the same one)", therefore OGR_G_GetLinearGeometry() is easier
to use.

OK, done in trunk r71514.

By now, v.in.ogr is peppered with #if GDAL_VERSION_NUM >= X, looks like at
some stage we should have two versions, one for GDAL 1.x, another one for
GDAL 2.x...
