(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.
