1d7c3fb7ee KQueue detect peer close without EVFILT_READ
Motivation:
The EPOLL transport uses EPOLLRDHUP to detect when the peer closes the write side of the socket. Currently KQueue is not able to mimic this behavior and the only way to detect if the peer has closed is to read. It may not always be appropriate to read for backpressure and other reasons at the application level.

Modifications:
- Support EVFILT_SOCK filter which provides notification when the peer closes the socket

Result:
KQueue transport has more consistent behavior with Epoll transport for detecting peer closure.

c8a23028ad fix UnixChannelUtil#isBufferCopyNeededForWrite
fix not execute unit test in transport-native-unix-common-tests module

Motivation:

- Commit 047da11 introduced an bug for still copy byteBuf for composed of n(n <= IOV_MAX) NIO direct buffers
- Commit 3c4dfed add UnixChannelUtilTest in transport-native-unix-common-tests module, but not execute in maven compile

as issue #6825, #6870

Modifications:

- modified UnixChannelUtil#isBufferCopyNeededForWrite(ByteBuf), and UnixChannelUtilTest
- move UnixChannelUtilTest into transport-native-unix-common module, and add packet scope method UnixChannelUtil#isBufferCopyNeededForWrite(ByteBuf, int)

Result:

- no copy byteBuf for composed of n(n <= IOV_MAX) NIO direct buffers
- auto execute unit tests in UnixChannelUtilTest and it is easier to mock IOV_MAX

047da11086 Correctly handle ByteBuf implementations which have no memoryAddress when writing to native transport
Motivation:

Commit 3c4dfed08a introduced a regression in handling buffers that have no memoryAddress.

Modifications:

Fix regression and also add unit tests.

Result:

It's possible again to write buffers without memory address.

3c4dfed08a Fix handle of ByteBuf with multi nioBuffer in EpollDatagramChannel and KQueueDatagramChannel
Motivation:
1. special handling of ByteBuf with multi nioBuffer rather than type of CompositeByteBuf (eg. DuplicatedByteBuf with CompositeByteBuf)
2. EpollDatagramUnicastTest and KQueueDatagramUnicastTest passed because CompositeByteBuf is converted to DuplicatedByteBuf before write to channel
3. uninitalized struct msghdr will raise error

Modifications:
1. isBufferCopyNeededForWrite(like isSingleDirectBuffer in NioDatgramChannel) checks wether a new direct buffer is needed
2. special handling of ByteBuf with multi nioBuffer in EpollDatagramChannel, AbstractEpollStreamChannel, KQueueDatagramChannel, AbstractKQueueStreamChannel and IovArray
3. initalize struct msghdr

Result:
handle of ByteBuf with multi nioBuffer in EpollDatagramChannel and KQueueDatagramChannel are ok

4c6d946fba KQueueSocket#setTrafficClass exceptions
Motivation:
MacOS will throw an error when attempting to set the IP_TOS socket option if IPv6 is available, and also when getting the value for IP_TOS.

Modifications:
- Socket#setTrafficClass and Socket#getTrafficClass should try to use IPv6 first, and check if the error code indicates the protocol is not supported before trying IPv4

Result:
Fixes https://github.com/netty/netty/issues/6741.

3cc4052963 New native transport for kqueue
Motivation:
We currently don't have a native transport which supports kqueue https://www.freebsd.org/cgi/man.cgi?query=kqueue&sektion=2. This can be useful for BSD systems such as MacOS to take advantage of native features, and provide feature parity with the Linux native transport.

Modifications:
- Make a new transport-native-unix-common module with all the java classes and JNI code for generic unix items. This module will build a static library for each unix platform, and included in the dynamic libraries used for JNI (e.g. transport-native-epoll, and eventually kqueue).
- Make a new transport-native-unix-common-tests module where the tests for the transport-native-unix-common module will live. This is so each unix platform can inherit from these test and ensure they pass.
- Add a new transport-native-kqueue module which uses JNI to directly interact with kqueue

Result:
JNI support for kqueue.
