       * java/io/FileDescriptor.java
       (SYNC): New constant.
       (DSYNC): Likewise.
       (getLength): Renamed from lenght() to match classpath's
       FileDescriptor.java.
       * java/io/RandomAccessFile.java
       (RandomAccessFile): Removed unneeded mode check, implemented mode
       "rws" and "rwd", merged documentation from classpath.
       (setLength): Reformatted.
       (length): Use new getLength() of FileDescriptor.
       * java/io/natFileDescriptorEcos.cc
       (getLength): Renamed from length().
       * java/io/natFileDescriptorPosix.cc
       (open): Implemented support for SYNC and DSYNC.
       (seek): Use getLength() instead of length().
       (getLength): Renamed from length().
       * java/io/natFileDescriptorWin32.cc
       (getLength): Renamed from length().
       (seek): Use getLength() instead of length().
       (available): Likewise.
       * gnu/java/nio/natFileChannelImpl.cc
       (size): Use getLength() instead of length().
