Convert all remaining geometric operators to new fmgr style. This

Browse Source 
allows fixing problems with operators that expected to be able to
return a NULL, such as the '#' line-segment-intersection operator
that tried to return NULL when the two segments don't intersect.
(See, eg, bug report from 1-Nov-99 on pghackers.)  Fix some other
bugs in passing, such as backwards comparison in path_distance().
