SIGSEGV in ST_GeomFromGeoJSON with empty list of coordinates

[mwanner]

As reported by Debian user Jérémy Lal postgis-2.1.0 crashes the Postgres backend when given the following query:

SELECT ST_GeomFromGeoJSON('{"type":"Polygon",
                            "bbox":[1,5,2,6],
                            "coordinates":[]}')::box2d;

I can reprodude this issue with 2.1.1. I found a related issue #2546 as well as commit r8690, which seems to have fixed this before, but given it's 2 years ago, I'm assuming that's included in 2.1.1.

This crashes on 2.1.1, 2.1.2, 2.0.4 for me so I pushed to 2.0.5. This doesn't seem to be quite same issue as the r8690 since all those crashme tests don't crash on my installs (I think those were completely missing coordinates — not case of empty coordinates)
