#3855: TWKB generations works too much on the heap
-------------------------+---------------------------

Component:  postgis      |    Version:  trunk

-------------------------+---------------------------
 Checking a profile of TWKB it becomes pretty clear that for large numbers
 of small objects it spends an inordinate amount of time allocating and
 deallocating memory, mostly handling bytebuffers on the heap. Sticking
 those buffers on the stack, and also having the buffers use a default
 static buffer initially makes things *much* faster.
