5aa7dc5daf adopt suggestions from Bentley and McIlroy (SP&E Nov 1993) 
to make qsort more robust:

	* use "ninther" to choose pivot.
	* use three-way partition to avoid quadratic
 	  behavior on all-one-value arrays.

also add tests suggested in that paper.

the immediate cause of the slowness we observed was
in fact none of these: the recursive call was sorting
data[0:m] instead of data[a:m].

also rename package to "sort" to match convention.
