[patch/testsuite/threads] add #include <stdlib.h>

[Michael Chastain <mec dot gnu at mindspring dot com>]

This patch includes <stdlib.h> in a few more files as required by the
Ansi C standard: a program must include a standard header before it can
use a standard library function.  gcc HEAD issues warnings about this
now.

This is the last bit of fluff to get gdb.threads working with gcc HEAD.
The results with gcc HEAD are now as good as the results with gcc 3.4.2,
for gdb.threads.

(There's one file left in gdb.mi that I know about).

I hope gcc doesn't add any more new warnings for a while.

Tested on native i686-pc-linux-gnu with gcc 2.95.3, gcc 3.3.4,
gcc 3.4.2, and gcc HEAD 20040914, with dwarf-2 and stabs+.

I am committing this now.
