9f726c2c8b Use explicit allspan list instead of 
trying to find all the places where
spans might be recorded.

Free can cascade into complicated
span manipulations that move them
from list to list; the old code had the
possibility of accidentally processing
a span twice or jumping to a different
list, causing an infinite loop.

unless given -d flag.

the resulting binary doesn't *use* any dynamic libraries,
it just has a reference to the dynamic linker and an

this is enough to make 6.out binaries that can be run

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);
}

5fe4cd83a8 do not set t->recur on basic types. 
the comment talked about printing, but now
t->recur is only used for typehash.
in typehash it is important to compute different
hashes for the different basic types.

add test that makes sure an interface { X() int8 }
cannot be used as interface { X() int64 }

5383e28ea0 change string([]byte) to pass array, rather than &a[0], 
to string convert.  if the byte array has length 0,
the computation of &a[0] throws an index bounds error.

for fixed size arrays, this ends up invoking arrays2d
unnecessarily, but it works.

ccede3e872 make syscall use strings for file names 
tweak os to adjust
move StringToBytes into syscall, at least for now

this program still works:

	package main

	import os "os"

	func main() {
		os.Stdout.WriteString("hello, world\n");
		a, b := os.NewFD(77).WriteString("no way");
		os.Stdout.WriteString(b.String() + "\n");
	}
