Runtime.java (_exit): Declare new package-private native.

2001-03-12  Bryce McKinlay  <bryce@albatross.co.nz>

	* java/lang/Runtime.java (_exit): Declare new package-private native.
	* java/lang/natRuntime.cc (_exit): Implemented. Same as exit() but
	without a security manager check.
	(exit): Call _exit after security check.
	* prims.cc (JvRunMain): Call Runtime._exit to shutdown the runtime
	"naturally".
	* java/lang/System.java (setSecurityManager): If a security manager
	is already in place, call checkPermission.
	* java/lang/ThreadGroup.java (uncaughtException): If printStackTrace()
	throws an exception, try to deal with it gracefully.
	* java/lang/ExceptionInInitializerError.java (printStackTrace):
	Only try to print the subordinate stack trace if "exception" is set.
	Print our class name first.
