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.

06436efaa1 [#5190] Ensure memory is not leaked when readEndOfLine(...) throws an exception.
Motivation:

We need to ensure we not retain the buffer until readEndOfLine(...) completes as otherwise we may leak memory in the case of an exception.

Modifications:

Only call retain after readEndOfLine(...) returns.

Result:

No more leak in case of exception while decoding redis messages.

7db9f454fe Fix decoding null bulk string of RedisDecoder
Motivation:

- `RedisBulkStringAggregator` raises errors for multiple null bulk strings.
- Null or empty bulk string has no content, but current `RedisDecoder` generates header and contents.

Modifications:

- Fix decoding null bulk string of `RedisDecoder` for `RedisBulkStringAggregator`.

Result:

- Fixes #5184.
