ThreadGroup.java: Merged with classpath.

2000-06-20  Bryce McKinlay  <bryce@albatross.co.nz>

	* java/lang/ThreadGroup.java: Merged with classpath.
	* prims.cc (_Jv_RunMain): Don't use 
ain_group'.
	* gnu/gcj/runtime/FirstThread.java: Remove ThreadGroup constructor
	argument.
	* java/lang/Thread.java (Thread): Bootstrap initial thread from
	ThreadGroup.root if Thread.currentThread is null. Honour the
	ThreadGroup's max priority setting.
