MappedByteBuffer*Stream:
- Validate active and GC'ed mapped-buffer count
in cleanAllSlices() via close() ..
- Fix missing unmapping last buffer in notifyLengthChangeImpl(),
branch criteria was off by one.
- cleanSlice(..) now also issues cleanBuffer(..) on the GC'ed entry,
hence if WeakReference is still alive, enforce it's release.
- cleanBuffer(..) reverts FLUSH_PRE_HARD -> FLUSH_PRE_SOFT
in case of an error.
- flush() -> flush(boolean metaData) to expose FileChannel.force(metaData).
- Add synchronous mode, flushing/syncing the mapped buffers when
in READ_WRITE mapping mode and issue FileChannel.force() if not READ_ONLY.
Above is implemented via flush()/flushImpl(..) for buffers and FileChannel,
as well as in syncSlice(..) for buffers only.
flush*()/syncSlice() is covered by:
- setLength()
- notifyLengthChange*(..)
- nextSlice()
Always issue flushImpl() in close().
- Windows: Clean all buffers in setLength(),
otherwise Windows will report:
- Windows: Catch MappedByteBuffer.force() IOException
- Optimization of position(..)
position(..) is now standalone to allow issuing flushSlice(..)
before gathering the new mapped buffer.
This shall avoid one extra cache miss.
Hence rename positionImpl(..) -> position2(..).
- All MappedByteBufferOutputStream.write(..) methods
issue syncSlice(..) on the last written current slice
to ensure new 'synchronous' mode is honored.

Unit tests:
- Ensure test files are being deleted
- TestByteBufferCopyStream: Reduced test file size to more sensible values.
