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.

2d4f7ba0cd printf as we know and love it. 
Plus print[ln] with the ability to print struct values.

Note for language mavens: if a "..." function passes its argument
to another "..." function, the argument is not wrapped again.  This
allows printf to call fprintf without extra manipulation. It's good
but needs to go in the spec.

This code works:
///
package main

import fmt "fmt"
import os "os"

type T struct { s string; a, b int }

func main() {
	P := fmt.Printer();
	P.printf("%s = %d with float value %.4f\n", "hi there", 7, 123.456);
	P.println("hi there", 7, 123.456);
	P.fprintf(os.Stdout, "%s = %d with float value %.4f\n", "hi there", 7, 123.456);
	P.println(T{"x", 7, 234}, "end of struct", 8, 9);
}
