Summary:  java.io.RandomAccessFile.skipBytes() seeks past EOF

Original Submission:  The Sun javadocs imply that skipBytes() should not skip
past the EOF of a file, and that's the way that JDK 1.4
behaves.  But the Classpath version will seek of into 
the distance.

This bug is exercised by Mauve testcase
    gnu.testlet.java.io.RandomAccessFile.raf.java
which goes into an infinite loop.

The bug is in the native code.  The lseek(2) syscall
can seek beyond the EOF position on Linux.  A 3rd lseek
call is needed to test for this, and a 4th to correct it.
