* Makefile.am: New friends for java/lang/Thread.h.
* prims.cc (runFirst): Removed.
(JvRunMain): Merged into _Jv_RunMain. Now just calls that.
(_Jv_RunMain): Now takes either a klass or class name parameter.
Create a gnu.gcj.runtime.FirstThread and attach the native thread
to that, then run it using _Jv_ThreadRun. Remove special handling of
jar files, instead pass is_jar parameter through to FirstThread.
* gcj/javaprims.h: Add prototypes for _Jv_ThreadRun and new variant
of _Jv_AttachCurrentThread.
* gnu/gcj/runtime/FirstThread.java (FirstThread): Now extends Thread.
(run): New method. Take care of looking up main class manifest
attribute and calling forName if neccessary. Then call call_main.
(call_main): New native method.
* gnu/gcj/runtime/natFirstThread.cc (call_main): New function, code
relocated from prims.cc. Look up and call main method.
* java/lang/Thread.java (run_): Removed.
* java/lang/natThread.cc (run_): Renamed to...
(_Jv_ThreadRun): this. JVMPI notification code moved to ...
(_Jv_NotifyThreadStart): here. New function.
(countStackFrames, destroy, resume, suspend, stop): Throw
UnsupportedOperationExceptions rather than JvFail'ing.
(_Jv_AttachCurrentThread): New variant takes a Thread argument.
Existing version wraps new variant.
