Major merge with Classpath.
Removed many duplicate files. * HACKING: Updated.x * classpath: Imported new directory. * standard.omit: New file. * Makefile.in, aclocal.m4, configure: Rebuilt. * sources.am: New file. * configure.ac: Run Classpath configure script. Moved code around to support. Disable xlib AWT peers (temporarily). * Makefile.am (SUBDIRS): Added 'classpath' (JAVAC): Removed. (AM_CPPFLAGS): Added more -I options. (BOOTCLASSPATH): Simplified. Completely redid how sources are built. Include sources.am. * include/Makefile.am (tool_include__HEADERS): Removed jni.h. * include/jni.h: Removed (in Classpath). * scripts/classes.pl: Updated to look at built classes. * scripts/makemake.tcl: New file. * testsuite/libjava.jni/jni.exp (gcj_jni_compile_c_to_so): Added -I options. (gcj_jni_invocation_compile_c_to_binary): Likewise. From-SVN: r102082

-/**
- * This class is used to implement a chain of event handlers. Dispatching
- * using this class is thread safe. Here is a quick example of how to
- * add and delete listeners using this class. For this example, we will
- * assume are firing <code>AdjustmentEvent</code>'s. However, this
- * same approach is useful for all events in the <code>java.awt.event</code>
- * package, and more if this class is subclassed.
- *
- * <p><code>
- * AdjustmentListener al;
- * public void addAdjustmentListener(AdjustmentListener listener)
- * {
- * al = AWTEventMulticaster.add(al, listener);
- * }
- * public void removeAdjustmentListener(AdjustmentListener listener)
- * {
- * al = AWTEventMulticaster.remove(al, listener);
- * }
- * </code>
- *
- * <p>When it come time to process an event, simply call <code>al</code>,
- * assuming it is not <code>null</code>, and all listeners in the chain will
- * be fired.
- *
- * <p>The first time <code>add</code> is called it is passed
- * <code>null</code> and <code>listener</code> as its arguments. This
- * starts building the chain. This class returns <code>listener</code>
- * which becomes the new <code>al</code>. The next time, <code>add</code>
- * is called with <code>al</code> and <code>listener</code> and the
- * new listener is then chained to the old.
