dd6b7969b7 Give a handler more control over how its buffers' read bytes are discarded.
This pull request adds two new handler methods: discardInboundReadBytes(ctx) and discardOutboundReadBytes(ctx) to ChannelInboundByteHandler and ChannelOutboundByteHandler respectively. They are called between every inboundBufferUpdated() and flush() respectively. Their default implementation is to call discardSomeReadBytes() on their buffers and a user can override this behavior easily. For example, ReplayingDecoder.discardInboundReadBytes() looks like the following:

    @Override
    public void discardInboundReadBytes(ChannelHandlerContext ctx) throws Exception {
        ByteBuf in = ctx.inboundByteBuffer();
        final int oldReaderIndex = in.readerIndex();
        super.discardInboundReadBytes(ctx);
        final int newReaderIndex = in.readerIndex();
        checkpoint -= oldReaderIndex - newReaderIndex;
    }

If a handler, which has its own buffer index variable, extends ReplayingDecoder or ByteToMessageDecoder, the handler can also override discardInboundReadBytes() and adjust its index variable accordingly.

0909878581 Read only when requested (read-on-demand)
This pull request introduces a new operation called read() that replaces the existing inbound traffic control method. EventLoop now performs socket reads only when the read() operation has been issued. Once the requested read() operation is actually performed, EventLoop triggers an inboundBufferSuspended event that tells the handlers that the requested read() operation has been performed and the inbound traffic has been suspended again. A handler can decide to continue reading or not.

Unlike other outbound operations, read() does not use ChannelFuture at all to avoid GC cost. If there's a good reason to create a new future per read at the GC cost, I'll change this.

This pull request consequently removes the readable property in ChannelHandlerContext, which means how the traffic control works changed significantly.

This pull request also adds a new configuration property ChannelOption.AUTO_READ whose default value is true. If true, Netty will call ctx.read() for you. If you need a close control over when read() is called, you can set it to false.

Another interesting fact is that non-terminal handlers do not really need to call read() at all. Only the last inbound handler will have to call it, and that's just enough. Actually, you don't even need to call it at the last handler in most cases because of the ChannelOption.AUTO_READ mentioned above.

There's no serious backward compatibility issue. If the compiler complains your handler does not implement the read() method, add the following:

public void read(ChannelHandlerContext ctx) throws Exception {
    ctx.read();
}

Note that this pull request certainly makes bounded inbound buffer support very easy, but itself does not add the bounded inbound buffer support.

03e68482bb Remove ChannelBuf/ByteBuf.Unsafe
- Fixes #826
Unsafe.isFreed(), free(), suspend/resumeIntermediaryAllocations() are not that dangerous. internalNioBuffer() and internalNioBuffers() are dangerous but it seems like nobody is using it even inside Netty. Removing those two methods also removes the necessity to keep Unsafe interface at all.

51e6519b67 Replace UnsafeByteBuf with ByteBuf.unsafe() again
* UnsafeByteBuf is gone. I added ByteBuf.unsafe() back.
* To avoid extra instantiation, all ByteBuf implementations implement the ByteBuf.Unsafe interface.
* To hide this implementation detail, all ByteBuf implementations are package-private.
* AbstractByteBuf and SwappedByteBuf are public and they do not implement ByteBuf.Unsafe because they don't need to.
* unwrap() is not an unsafe operation anymore.
* ChannelBuf also has unsafe() and Unsafe. ByteBuf.Unsafe extends ChannelBuf.unsafe(). ChannelBuf.unsafe() provides free() operation so that a user does not need to down-cast the buffer in freeInbound/OutboundBuffer().

81e2db10fa ByteBufAllocator API w/ ByteBuf perf improvements
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
