Labelling lines with zero lengths may cause the application to crash

[szekerest]

To reproduce this a LINE layer should be configured with TRANSFORM FALSE and the shapefile should contain a line with zero length (all points are at the same location).

The crash location is at:

                mapserver!msLineLabelPoint+0x209 [mapprimitive.c @ 1717]
		mapserver!msPolylineLabelPoint+0x141 [mapprimitive.c @ 1648]
		mapserver!lineLayerDrawShape+0x41c [mapdraw.c @ 1854]
		mapserver!msDrawShape+0x80d [mapdraw.c @ 2169]
		mapserver!msDrawVectorLayer+0x7be [mapdraw.c @ 1164]
		mapserver!msDrawLayer+0x3a3 [mapdraw.c @ 813]
		mapserver!msDrawMap+0x415 [mapdraw.c @ 403]
		mapscript!CSharp_mapObj_draw+0xd

Note: Not all of the data providers support returning such invalid geometries, the shapefile driver does.
