* 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(). From-SVN: r66755

* This method initializes a new instance of <code>RandomAccessFile</code>

* The access mode is either "r" for read only access or "rw" for read
|

* write access.
|

* The access mode is either "r" for read only access, "rw" for read

* write access, "rws" for synchronized read/write access of both

* content and metadata, or "rwd" for read/write access
|

* where only content is required to be synchronous.
|

* <p>
|

* Note that a <code>SecurityManager</code> check is made prior to

||||
* opening the file to determine whether or not this file is allowed to
