Major merge with Classpath.

Browse Source 
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.
