* gnu/java/nio/channels/FileChannelImpl.java (truncate): Only truncate
when size is smaller.
* java/io/RandomAccessFile.java (setLength): Use truncate for
shrinking the file and seek plus write for expanding the file.

* gnu/java/nio/channels/natFileChannelPosix.cc
(implTruncate): Always save current position. Only reposition file
pointer to where we started if not beyond new lenght. Reposition file
pointer to file length if it points beyond the end of file.
