3a9f472161 Make retained derived buffers recyclable
Related: #4333 #4421 #5128

Motivation:

slice(), duplicate() and readSlice() currently create a non-recyclable
derived buffer instance. Under heavy load, an application that creates a
lot of derived buffers can put the garbage collector under pressure.

Modifications:

- Add the following methods which creates a non-recyclable derived buffer
  - retainedSlice()
  - retainedDuplicate()
  - readRetainedSlice()
- Add the new recyclable derived buffer implementations, which has its
  own reference count value
- Add ByteBufHolder.retainedDuplicate()
- Add ByteBufHolder.replace(ByteBuf) so that..
  - a user can replace the content of the holder in a consistent way
  - copy/duplicate/retainedDuplicate() can delegate the holder
    construction to replace(ByteBuf)
- Use retainedDuplicate() and retainedSlice() wherever possible
- Miscellaneous:
  - Rename DuplicateByteBufTest to DuplicatedByteBufTest (missing 'D')
  - Make ReplayingDecoderByteBuf.reject() return an exception instead of
    throwing it so that its callers don't need to add dummy return
    statement

Result:

Derived buffers are now recycled when created via retainedSlice() and
retainedDuplicate() and derived from a pooled buffer

5b48fc284e Make OIO/NIO/EPOLL autoReadClear consistent
Motivation:
OIO/NIO use a volatile variable to track if a read is pending. EPOLL does not use a volatile an executes a Runnable on the event loop thread to set readPending to false. These mechansims should be consistent, and not using a volatile variable is preferable because the variable is written to frequently in the event loop thread.
OIO also does not set readPending to false before each fireChannelRead operation and may result in reading more data than the user desires.

Modifications:
- OIO/NIO should not use a volatile variable for readPending
- OIO should set readPending to false before each fireChannelRead

Result:
OIO/NIO/EPOLL are more consistent w.r.t. readPending and volatile variable operations are reduced

3e5dcb5f3e [#3806] Setting WRITE_BUFFER_LOW_WATER_MARK before WRITE_BUFFER_HIGH_WATER_MARK results in an internal Exception
Motivation:

Setting the WRITE_BUFFER_LOW_WATER_MARK before WRITE_BUFFER_HIGH_WATER_MARK results in an internal Exception (appears only in the logs) if the value is larger than the default high water mark value. The WRITE_BUFFER_HIGH_WATER_MARK call appears to have no effect in this context.

Setting the values in the reverse order works.

Modifications:

- deprecated ChannelOption.WRITE_BUFFER_HIGH_WATER_MARK and
ChannelOption.WRITE_BUFFER_LOW_WATER_MARK.
- add one new option called ChannelOption.WRITE_BUFFER_WATER_MARK.

Result:
The high/low water mark values limits caused by default values are removed.

Setting the WRITE_BUFFER_LOW_WATER_MARK before WRITE_BUFFER_HIGH_WATER_MARK results in an internal Exception (appears only in the logs) if the value is larger than the default high water mark value. The WRITE_BUFFER_HIGH_WATER_MARK call appears to have no effect in this context.

Setting the values in the reverse order works.

8ba4b63cb6 OioServerChannel Default Max Messages Per Read Too High
Motivation:
A few implementations of OioServerChannel have a default max messages per read set to 16. We should set the default to 1 to prevent blocking on a read before setting a socket that has just been accepted.

Modifications:
- OioSctpServerChannel and OioServerSocketChannel metadata changed to use the default (1) max messages per read

Result:
Oio based servers will complete accepting a socket before potentially blocking waiting to accept other sockets.

4eaa59d516 Improve SctpMessage.hashCode method
Motivation:

Not all fields of SctpMessage which used to check message equality are used
to generate hashcode.

Modifications:

Use value of 'unordered' field in hashCode method.

Result:

Better hash function of SctpMessage.

9e1e4f79c7 Fix SctpMessage.duplicate() behavior
Motivation:

SctpMessage.duplicate() copied message content that leads to additional buffer
allocation and memory copying.

Modifications:

Duplicate message content instead of copying it.

Result:

Better performace and less memory consumption.

c22f1aa4ac Clear selectedKeys in OioSctpChannel.doReadMessages
Motivation:
The fix for https://github.com/netty/netty/issues/3884 breaks SctpEchoTest because Selector.select will always return 0 if you do not clear last selectedKeys.

Modifications:
Clear readSelector.selectedKeys() if it is not empty.

Result:
SctpEchoTest is green again.

99b11c95b4 [#4327] Ensure toString() will not throw IllegalReferenceCountException
Motivation:

As toString() is often used while logging we need to ensure this produces no exception.

Modifications:

Ensure we never throw an IllegalReferenceCountException.

Result:

Be able to log without produce exceptions.

56cc0bbd4c OioSctpChannel iterating over selected keys
Motivation:
OioSctpChannel.doReadMessages is iterating over the selected keys, and ignoring each selected key. It is not known why this is needed and no other channel implementation does this.

Modifications:
- Stop iterating over selected keys, and just read like other channels

Result:
No unnecessary iteration in OioSctpChannel.doReadMessages.

cf171ff525 maxBytesPerRead channel configuration
Motiviation:
The current read loops don't fascilitate reading a maximum amount of bytes. This capability is useful to have more fine grain control over how much data is injested.

Modifications:
- Add a setMaxBytesPerRead(int) and getMaxBytesPerRead() to ChannelConfig
- Add a setMaxBytesPerIndividualRead(int) and getMaxBytesPerIndividualRead to ChannelConfig
- Add methods to RecvByteBufAllocator so that a pluggable scheme can be used to control the behavior of the read loop.
- Modify read loop for all transport types to respect the new RecvByteBufAllocator API

Result:
The ability to control how many bytes are read for each read operation/loop, and a more extensible read loop.

6c025b2044 Add support for SCTP 'unordered' flag.
Motivation:

Some SCTP applications require the SCTP unordered flag.
This flag was not exposed by Netty so applications were unable
to use it.

Modifications:

- Add unordered flag to SctpMessage.
- {Nio,Oio}SctpChannel pass unordered flag to MessageInfo on write.
- SctpOutboundByteStreamHandler may optionally request unordered
  delivery for all outbound messages.
- Added test case to SctpEchoTest using unordered flag.

Result:

Fixes #3698. New constructors and methods added to SctpMessage and
SctpOutboundByteStreamHandler, but changes are backward compatible.

b4b14ea19f Ensure backward-compability with 4.0
Motivation:

Each different *ChannelOption did extend ChannelOption in 4.0, which we changed in 4.1. This is a breaking change in terms of the API so we need to ensure we keep the old hierarchy.

Modifications:

- Let all *ChannelOption extend ChannelOption
- Add back constructor and mark it as @deprecated

Result:

No API breakage between 4.0 and 4.1

286b89933c Allow to obtain RecvByteBufAllocator.Handle to allow more flexible implementations
Motivation:

At the moment it's only possible for a user to set the RecvByteBufAllocator for a Channel but not access the Handle once it is assigned. This makes it hard to write more flexible implementations.

Modifications:

Add a new method to the Channel.Unsafe to allow access the the used Handle for the Channel. The RecvByteBufAllocator.Handle is created lazily.

Result:

It's possible to write more flexible implementatons that allow to adjust stuff on the fly for a Handle that is used by a Channel
