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.
