Bug 1080 - Add read support for memory mapped big file I/O via specialized InputStream impl., incl. mark/reset

- ByteBufferInputStream simply impl. InputStream for an arbitrary 2MiB restricted ByteBuffer
  - Users may only need a smaller implementation for 'smaller' file sizes
    or for streaming a [native] ByteBuffer.

- MappedByteBufferInputStream impl. InputStream for any file size,
  while slicing the total size to memory mapped buffers via the given FileChannel.
  The latter are mapped lazily and diff. flush/cache methods are supported
  to ease virtual memory usage.

- TestByteBufferInputStream: Basic unit test for basic functionality and perf. stats.
