MappedByteFileBuffer.java, [...]: Removed

Browse Source 
2003-06-20  Michael Koch  <konqueror@gmx.de>

	* gnu/java/nio/MappedByteFileBuffer.java,
	gnu/java/nio/natMappedByteFileBuffer.cc:
	Removed
	* java/nio/MappedByteBufferImpl.java:
	New file.
	* gnu/java/nio/FileChannelImpl.java:
	Use MappedByteBufferImpl instead of MappedByteFileBuffer.
	* Makefile.am
	(ordinary_java_source_files): Removed
	gnu/java/nio/MappedByteFileBuffer.java and added
	java/nio/MappedByteBufferImpl.java.
	(nat_source_files): Removed gnu/java/nio/natMappedByteFileBuffer.cc
	* Makefile.in: Regenerated.
