dfa3bbbf00 Add support for Client Subnet in DNS Queries (RFC7871)
Motivation:

RFC7871 defines an extension which allows to request responses for a given subset.

Modifications:

- Add DnsOptPseudoRrRecord which can act as base class for extensions based on EDNS(0) as defined in RFC6891
- Add DnsOptEcsRecord to support the Client Subnet in DNS Queries extension
- Add tests

Result:

Client Subnet in DNS Queries extension is now supported.

8cf90f0512 [#5760] Do not change writerIndex when decode DnsPtrRecord
Motivation:

We need to not change the original writerIndex when decode a DnsPtrRecord as otherwise we will not be able to decode other records that follow it.

Modifications:

Slice the data out and so not increase the writerIndex.

Result:

No more problems when decoding.

3288cacf8d Pluggable resource leak detector
Allow users of Netty to plug in their own leak detector for the purpose
of instrumentation.

Motivation:

We are rolling out a large Netty deployment and want to be able to
track the amount of leaks we're seeing in production via custom
instrumentation. In order to achieve this today, I had to plug in a
custom `ByteBufAllocator` into the bootstrap and have it initialize a
custom `ResourceLeakDetector`. Due to these classes mostly being marked
`final` or having private or static methods, a lot of the code had to
be copy-pasted and it's quite ugly.

Modifications:

* I've added a static loader method for the `ResourceLeakDetector` in
`AbstractByteBuf` that tries to instantiate the class passed in via the
`-Dio.netty.customResourceLeakDetector`, otherwise falling back to the
default one.
* I've modified `ResourceLeakDetector` to be non-final and to have the
reporting broken out in to methods that can be overridden.

Result:

You can instrument leaks in your application by just adding something
like the following:

```java
public class InstrumentedResourceLeakDetector<T> extends
ResourceLeakDetector<T> {

    @Monitor("InstanceLeakCounter")
    private final AtomicInteger instancesLeakCounter;

    @Monitor("LeakCounter")
    private final AtomicInteger leakCounter;

    public InstrumentedResourceLeakDetector(Class<T> resource) {
        super(resource);
        this.instancesLeakCounter = new AtomicInteger();
        this.leakCounter = new AtomicInteger();
    }

    @Override
    protected void reportTracedLeak(String records) {
        super.reportTracedLeak(records);
        leakCounter.incrementAndGet();
    }

    @Override
    protected void reportUntracedLeak() {
        super.reportUntracedLeak();
        leakCounter.incrementAndGet();
    }

    @Override
    protected void reportInstancesLeak() {
        super.reportInstancesLeak();
        instancesLeakCounter.incrementAndGet();
    }
}
```

c7a0a0f325 [#5391] DnsNameResolver does not resolve property A+CNAME answer
Motivation:

The current DnsNameResolver fails to resolve an A+CNAME answer. For example:

dig moose.rmq.cloudamqp.com

...
;; ANSWER SECTION:
moose.rmq.cloudamqp.com. 1800   IN  CNAME   ec2-54-152-221-139.compute-1.amazonaws.com.
ec2-54-152-221-139.compute-1.amazonaws.com. 583612 IN A 54.152.221.139
...

The resolver constructs a map of cnames but forgets the trailing "." in the values which lead to not resolve the A record.

Modifications:

Reuse the code of DefaltDnsRecordDecoder which correctly handles the trailing dot.

Result:

Correctly resolve.

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

9229ed98e2 [#5088] Add annotation which marks packages/interfaces/classes as unstable
Motivation:

Some codecs should be considered unstable as these are relative new. For this purpose we should introduce an annotation which these codecs should us to be marked as unstable in terms of API.

Modifications:

- Add UnstableApi annotation and use it on codecs that are not stable
- Move http2.hpack to http2.internal.hpack as it is internal.

Result:

Better document unstable APIs.

4b38b72a0d Fix incorrect name encoding/decoding in DNS records
Motivation:

- The decoded name should always end with a dot (.), but we currently
  strip it, which is incorrect.
  - (O) 0 -> "."
  - (X) 0 -> ""
  - (O) 5 netty 2 io 0 -> "netty.io."
  - (X) 5 netty 2 io 0 -> "netty.io"
- The encoded name should end with a null-label, which is a label whose
  length is 0, but we currently append an extra NUL, causing FORMERR(1)
  on a strict DNS server:
  - (O) . -> 0
  - (X) . -> 0 0
  - (O) netty.io. -> 5 netty 2 io 0
  - (X) netty.io. -> 5 netty 2 io 0 0

Modifications:

- Make sure to append '.' when decoding a name.
- Improve index checks so that the decoder can raise
  CorruptFrameException instead of IIOBE
- Do not encode extra NUL
- Add more tests

Result:

Robustness and correctness

6bf7e24389 [#5014] Correctly encode / decode zero-length names when encoding DnsRecords.
Motivation:

Zero-length names needs to be "prefixed" by the length as well when encoded into a ByteBuf. Also some servers not correctly prefix these so we should ensure we can workaround this and even decode in such case.

Modifications:

- Always encode the length of the name into the ByteBuf even if its zero-length.
- If there are no readable bytes for the name just asume its an empty name to workaround dns servers that not fully respect the RFC.

Result:

Correctly encode zero-length names and be able to decode empty names even when the rfc is not strictly followed.

48506f5b05 [#4993] Correctly handle trailing dot in DNS requests and responses for the hostname.
Motivation:

We need to handle the trailing dot in the correct manner when creating DNS questions and responses.

Modifications:

- Add a trailing dot if not given to the hostname when construct a AbstractDnsRecord (this is the same as dig does).

Result:

Correctly handle trailing dots.

58c63b7888 Add support for directly decoding/encoding DNS PTR Records
Motivation:

The current implementation will provide a DnsRawRecord, which, while
containing the host name it resolves to, would require the user to
decode the name using the decode method currently private to
DefaultDnsRecordDecoder, which in fact means copying it.

Modifications:

Introduce DnsPtrRecord, which is a specialization of DnsRecord which
provides a decoded host name.

Result:

PTR Records are much easier to work with, as the name is decoded already.
