First installation of potential updates for M4
- Change methods that take a CompletionHandler to return void
  (API changes for now, more implementation changes later)
- CompletionHandler#cancelled no longer needed
- AsynchronousFileChannel#close no longer shuts down thread pool
- Cancel of AsynchronousSocketChannel read or write operation disabled both (unix)
- FileChannel#tryLock didn't declare all exceptions
- Added java.nio.file.attribute.FileTime to represent file timestamp
- Allow setTimes attempt to set timestamps that pre-date epoch
- Re-work FileRef to allow it be implemented more widely (by URL for example)
- Move type unsafe access to attribues to FileRef
- Eliminate some clutter from Inputs/Outputs
- Add Files#createDirectories (mkdir -p)
- Remove Files#withDirectory
- Remove DirectoryStreamFilters (not as useful as originally expected)
- Path#toRealPath(false) fails with broken sym link (unix)
- FileSystem#getPath(String) didn't reject paths strings with embedded nulls (unix)
- Initial changes to support thread agnostic I/O (win server 2008)
- Remove useless echo server sample
