FileChannelImpl.java, [...]: Removed.

2003-07-13  Michael Koch  <konqueror@gmx.de>

	* gnu/java/nio/FileChannelImpl.java,
	gnu/java/nio/natFileChannelImpl.cc: Removed.
	* java/io/FileInputStream.java,
	java/io/FileOutputStream.java,
	java/io/RandomAccessFile.java,
	java/nio/MappedByteBufferImpl.java:
	Import java.nio.channels.FileChannelImpl instead of
	gnu.java.nio.FileChannelImpl.
	* java/nio/channels/FileChannelImpl.java,
	java/nio/channels/natFileChannelImpl.cc:
	New files.
	* Makefile.am
	(ordinary_java_source_files):
	Removed gnu/java/nio/FileChannelImpl.java and added
	java/nio/channels/FileChannelImpl.java.
	(nat source_files):
	Removed gnu/java/nio/natFileChannelImpl.cc and added
	java/nio/channels/natFileChannelImpl.cc.
	* Makefile.in: Regenerated.
