ByteBufAllocator API w/ ByteBuf perf improvements

Browse Source 
This commit introduces a new API for ByteBuf allocation which fixes
issue #643 along with refactoring of ByteBuf for simplicity and better
performance. (see #62)

A user can configure the ByteBufAllocator of a Channel via
ChannelOption.ALLOCATOR or ChannelConfig.get/setAllocator().  The
default allocator is currently UnpooledByteBufAllocator.HEAP_BY_DEFAULT.

To allocate a buffer, do not use Unpooled anymore. do the following:

  ctx.alloc().buffer(...); // allocator chooses the buffer type.
  ctx.alloc().heapBuffer(...);
  ctx.alloc().directBuffer(...);

To deallocate a buffer, use the unsafe free() operation:

  ((UnsafeByteBuf) buf).free();

The following is the list of the relevant changes:

- Add ChannelInboundHandler.freeInboundBuffer() and
  ChannelOutboundHandler.freeOutboundBuffer() to let a user free the
  buffer he or she allocated. ChannelHandler adapter classes implement
  is already, so most users won't need to call free() by themselves.
  freeIn/OutboundBuffer() methods are invoked when a Channel is closed
  and deregistered.

- All ByteBuf by contract must implement UnsafeByteBuf. To access an
  unsafe operation: ((UnsafeByteBuf) buf).internalNioBuffer()

- Replace WrappedByteBuf and ByteBuf.Unsafe with UnsafeByteBuf to
  simplify overall class hierarchy and to avoid unnecesary instantiation
  of Unsafe instances on an unsafe operation.

- Remove buffer reference counting which is confusing

- Instantiate SwappedByteBuf lazily to avoid instantiation cost

- Rename ChannelFutureFactory to ChannelPropertyAccess and move common
  methods between Channel and ChannelHandlerContext there. Also made it
  package-private to hide it from a user.

- Remove unused unsafe operations such as newBuffer()

- Add DetectionUtil.canFreeDirectBuffer() so that an allocator decides
  which buffer type to use safely
