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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@102082 138bc75d-0d04-0410-961f-82ee72b054a4

-/**
- * <p>This class is used as an opaque representation of cryptographic
- * parameters.</p>
- *
- * <p>An <code>AlgorithmParameters</code> object for managing the parameters
- * for a particular algorithm can be obtained by calling one of the
- * <code>getInstance()</code> factory methods (static methods that return
- * instances of a given class).</p>
- *
- * <p>There are two ways to request such an implementation: by specifying
- * either just an algorithm name, or both an algorithm name and a package
- * provider.</p>
- *
- * <ul>
- * <li>If just an algorithm name is specified, the system will determine if
- * there is an AlgorithmParameters implementation for the algorithm requested
- * available in the environment, and if there is more than one, if there is
- * a preferred one.</li>
- * <li>If both an algorithm name and a package provider are specified, the
- * system will determine if there is an implementation in the package
- * requested, and throw an exception if there is not.</li>
- * </ul>
- *
- * <p>Once an <code>AlgorithmParameters</code> object is returned, it must be
- * initialized via a call to <code>init()</code>, using an appropriate
- * parameter specification or parameter encoding.</p>
- *
- * <p>A transparent parameter specification is obtained from an
- * <code>AlgorithmParameters</code> object via a call to
- * <code>getParameterSpec()</code>, and a byte encoding of the parameters is
- * obtained via a call to <code>getEncoded()</code>.</p>
