patch_tester.sh (initialization): Initialize svnpatch and stop.

2008-03-10  Janis Johnson  <janis187@us.ibm.com>

	* patch_tester.sh (initialization): Initialize svnpatch and stop.
	(usage): Add -svnpath and -stop.	
	(makedir): New.
	(argument handling): Process -stop and -svnpath.
	(setup code): Use makedir, error out if initial svn checkout fails.
	(update): Use svnpath.  Invoke contrib/gcc_update.
	(apply_patch): Require that patch was created at top level.  Use eval
	with option variables.  Don't use bootstrap target for make.  Verify
	that some tests were run.
	(bootntest_patched): Use snvpath.
	(main loop): For -stop, exit when there are no more patches to test.
