Comment (by nicklas):

 Now I've done two commits to spike /nicklas/distcalc

 r4714 is renaming to st_closestpoint as discussed above.
 I also applied the hack with st_convexhull for max-distance functions.
 Because they then have to be below st_convexhull in the sql-file I moved
 all the new functions down do the bottom before the sql-functions.

 The other commit r4715 to the spike is the new subgeometry handling. If it
 shows to have big problems please try before r4715 to see if the problem
 is caused before or after that.

 It now passes the regression tests and gives the same answer at my usual
 test-cases. I also think it seems to perform well even when there is no
 sub-geoms.
