#286: Change "no SRID" SRID to 0

Comment(by strk):
As of r7963 we do threat SRID<=0 all the same (as UNKNOWN).
Returning UNKNOWN srid as 0 (rather than -1) may still have backward
compatibility issues with code checking values against a literal -1 to
mean UNKNOWN. Note that some literal -1 values may also be in dataspace
(geometry_columns.srid, topology.topology.srid).
