07a641900c transport-native-kqueue libraries should not lazy link
Motivation:
We rely upon the linker being non-lazy to test compatibility the native library compatibility for kqueue, but the default mode of operation is to lazy link.

Modifications:
- We should modify the build scripts to inform the linker that this library should not be lazy linked
- Error messages changes
dyld: lazy symbol binding failed: Symbol not found: _clock_gettime

java.lang.UnsatisfiedLinkError: unsupported JNI version 0xFFFFFFFF required by .../libnetty-transport-native-kqueue.dylib

Result:
Link errors are detected upon library load time.

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

83de77fbe5 Make Native loading work better with Java 8
Motivation:
Enable static linking for Java 8.  These commits are the same as those introduced to netty tcnative.  The goal is to allow lots of JNI libraries to be statically linked together without having conflict `JNI_OnLoad` methods.

Modification:
* add JNI_OnLoad suffixes to enable static linking
* Add static names to the list of libraries that try to be loaded
* Enable compiling with JNI 1.8
* Sort includes

Result:
Enable statically linked JNI code.

b985615522 Fix compiler warnings in netty Epoll and unix common
Motivation:
Google requires stricter compilation by adding -Werror and enabling many other warnings.

Modification:

* fix warning caused by -Wmissing-braces

* Use the address of `sendmmsg` rather than the function itself when
checking for presence.  This resovles the warning caused by
`-Wpointer-bool-conversion`.

More detail:
When compiling on Linux, `sendmmsg` is always present, so the
function is always nonnull.  When compiling elsewhere, the
function is defined as `__attribute__((weak))` which means it
may be absent at link time.  This is controlled by
`IO_NETTY_SENDMMSG_NOT_FOUND`, which is off by default.

The reason for the error is due to the risk of accidentally not
calling the function.  By adding `&` before the function, there
is no ambiguity.  (the result of the fn call cannot have its
address taken.)

* use != to check for sendmmsg

Result:
Easier compilation.

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.

0b0309624a Correctly parse package-prefix if the jni lib is contained in a path that matches the library name.
Motivation:

We used strstr to find the path to the library, which fails if the library is contained in a directory that also matches the library name.

Modifications:

- Introduce netty_unix_util_strstr_last which will return a pointer which points to the last accourance and so not fails if the direct also matches the library name.

Result:

Be able to load the library in all cases.

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.

9e62c79574 Correctly include all modules during build
Motivation:

To ensure the release plugin works correctly we need to ensure all modules are included during build.

Modification:

- Include all modules
- Skip compilation and tests for native code when not supported but still include the module and build the jar

Result:

Build and release works again

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.
