Fix "path" infrastructure bug affecting jsonb_set()
jsonb_set() and other clients of the setPathArray() utility function
could get spurious results when an array integer subscript is provided
that is not within the range of int.
To fix, ensure that the value returned by strtol() within setPathArray()
is within the range of int; when it isn't, assume an invalid input in
line with existing, similar cases. The path-orientated operators that
appeared in PostgreSQL 9.3 and 9.4 do not call setPathArray(), and
already independently take this precaution, so no change there.
