8d99aa1235 Simplify WebSocket handlers constructor arguments hell #9698 (#9699)
### Motivation:

Introduction of `WebSocketDecoderConfig` made our server-side code more elegant and simpler for support.

However there is still some problem with maintenance and new features development for WebSocket codecs (`WebSocketServerProtocolHandler`, `WebSocketServerProtocolHandler`).

Particularly, it makes me ~~crying with blood~~ extremely sad to add new parameter and yet another one constructor into these handlers, when I want to contribute new feature.

### Modification:

I've extracted all parameters for client and server WebSocket handlers into config/builder structures, like it was made for decoders in PR #9116.

### Result:

* Fixes #9698: Simplify WebSocket handlers constructor arguments hell
* Unblock further development in this module (configurable close frame handling on server-side; automatic close-frame sending, when missed; memory leaks on protocol violations; etc...)

Bonuses:

* All defaults are gathered in one place and could be easily found/reused.
* New API greatly simplifies usage, but does NOT allow inheritance or modification.
* New API would simplify long-term maintenance of WebSockets module.

### Example

    WebSocketClientProtocolConfig config = WebSocketClientProtocolConfig.newBuilder()
        .webSocketUri("wss://localhost:8443/fx-spot")
        .subprotocol("trading")
        .handshakeTimeoutMillis(15000L)
        .build();
    ctx.pipeline().addLast(new WebSocketClientProtocolHandler(config));

HttpClientCodec need to keep request / response pairs in sync all the… (#9721)
Motivation:

At the moment we miss to poll the method queue when we see an Informational response code. This can lead to out-of-sync of request / response pairs when later try to compare these.

Modifications:

Always poll the queue correctly

Result:

Always compare the correct request / response pairs

816350fba1 Respect all informational status codes. (#9712)
Motivation:

HTTP 102 (WebDAV) is not correctly treated as an informational response

Modification:

Delegate all `1XX` status codes to superclass, not just `100` and `101`.

Result:

Supports WebDAV response.
Removes a huge maintenance [headache](https://github.com/line/armeria/pull/2210) in Armeria which has forked the class for these features

8674ccfcd2 Fix indexOutOfBoundsException when multipart/form-data is incorrect value (#9688)
Motivation:

HttpPostRequestDecoder.splitHeaderContentType() throws a StringIndexOutOfBoundsException when it parses a Content-Type header that starts with a semicolon ;. We should skip the execution for incorrect multipart form data.


Modification:

Avoid invocation of HttpPostRequestDecoder#splitHeaderContentType(...) for incorrect multipart form data content-type.

Result:

Fixes #8554

Use @SuppressJava6Requirement for animal sniffer plugin to ensure we always guard correctly (#9655)
Motivation:

We can use the `@SuppressJava6Requirement` annotation to be more precise about when we use Java6+ APIs. This helps us to ensure we always protect these places.

Modifications:

Make use of `@SuppressJava6Requirement` explicit

Result:

Fixes https://github.com/netty/netty/issues/2509.

e0b15ed952 [DOC] Add CWE-113 warning to DefaultHttpHeaders constructor (#9646)
### Motivation:

I've now found two libraries that use Netty to be vulnerable to [CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')](https://cwe.mitre.org/data/definitions/113.html) due to using `new DefaultHttpHeaders(false)`.

Some part of me hopes that this warning will help dissuade library authors from disabling this important security check.

### Modification:

Add documentation to `DefaultHttpHeaders(boolean)` to warn about the implications of `false`.

### Result:

This improves the documentation on `DefaultHttpHeaders`.

Correctly handle whitespaces in HTTP header names as defined by RFC7230#section-3.2.4 (#9585)
Motivation:

When parsing HTTP headers special care needs to be taken when a whitespace is detected in the header name.

Modifications:

- Ignore whitespace when decoding response (just like before)
- Throw exception when whitespace is detected during parsing
- Add unit tests

HttpPostStandardRequestDecoder leaks memory when constructor throws ErrorDataDecoderException. (#9517)
Motivation:

Currently when HttpPostStandardRequestDecoder throws a ErrorDataDecoderException during construction we leak memory. We need to ensure all is released correctly.

Modifications:

- Call destroy() if parseBody() throws and rethrow the ErrorDataDecoderException
- Add unit test

Motivation:

Some of the links in javadoc point to the obsolete drafts of HTTP/2
specifications. We should point them to the latest RFC 7540 or 7541.

Modifications:

Update links from `draft-ietf-httpbis-*` to the `rfc7540` and `rfc7541`.

Result:

Correct links in javadoc.

85fcf4e581 Use AppendableCharSequence.charAtUnsafe(int) in HttpObjectDecoder (#9492)
Motivation:

`HttpObjectDecoder` pre-checks that it doesn't request characters
outside of the `AppendableCharSequence`'s length. `0` is always allowed
because the minimal length of `AppendableCharSequence` is `1`. We can
legally skip index check by using
`AppendableCharSequence.charAtUnsafe(int)` in all existing cases in
`HttpObjectDecoder`.

Modifications:

- Use `AppendableCharSequence.charAtUnsafe(int)` instead of
`AppendableCharSequence.charAt(int)` in `HttpObjectDecoder`.

Result:

No unnecessary index checks in `HttpObjectDecoder`.

Ensure we replace WebSocketServerProtocolHandshakeHandler before doing the handshake (#9472)
Motivation:

We need to ensure we replace WebSocketServerProtocolHandshakeHandler before doing the actual handshake as the handshake itself may complete directly and so forward pending bytes through the pipeline.

Modifications:

Replace the handler before doing the actual handshake.

cbc8fc4428 Fix HttpUtil.getCharset to not throw illegal charset exception (#9439)
Motivation:

If the HttpUtil.getCharset method is called with an illegal charset like
"charset=!illegal!" it throws an IllegalCharsetNameException. But the javadoc
states, that defaultCharset is returned if incorrect header value. Since the
client sending the request sets the header value this should not crash.

Modification:

HttpUtil.getCharset catches the IllegalCharsetNameException and returns the
defualt value.

Result:

HttpUtil.getCharset does not throw IllegalCharsetNameException any more.

7c5a3c5898 Allow to turn off Utf8FrameValidator creation for websocket with Bina… (#9417)
…ryWebSocketFrames

Motivation:

`Utf8FrameValidator` is always created and added to the pipeline in `WebSocketServerProtocolHandler.handlerAdded` method. However, for websocket connection with only `BinaryWebSocketFrame`'s UTF8 validator is unnecessary overhead. Adding of `Utf8FrameValidator` could be easily avoided by extending of `WebSocketDecoderConfig` with additional property.

Specification requires UTF-8 validation only for `TextWebSocketFrame`.

Modification:

Added `boolean WebSocketDecoderConfig.withUTF8Validator` that allows to avoid adding of `Utf8FrameValidator` during pipeline initialization.

Result:

Less overhead when using only `BinaryWebSocketFrame`within web socket.

1194577bd0 Decrease the level of logging in WebSocketFrameEncoder/Decoder (#9415)
Motivation:

Our QA servers are spammed with this messages:

13:57:51.560 DEBUG- Decoding WebSocket Frame opCode=1
13:57:51.560 DEBUG- Decoding WebSocket Frame length=4
I think this is too much info for debug level. It is better to move it to trace level.

Modification:

logger.debug changed to logger.trace for WebSocketFrameEncoder/Decoder

Result:

Less messages in Debug mode.

1e8c0c59f1
Use allocator when constructing ByteBufHolder sub-types or use Unpool… (#9377)
Motivation:

In many places Netty uses Unpooled.buffer(0) while should use EMPTY_BUFFER. We can't change this due to back compatibility in the constructors but can use Unpooled.EMPTY_BUFFER in some cases to ensure we not allocate at all. In others we can directly use the allocator either from the Channel / ChannelHandlerContext or the request / response.

Modification:

- Use Unpooled.EMPTY_BUFFER where possible
- Use allocator where possible

Result:

Fixes #9345 for websockets and http package

Add websocket encoder / decoder in correct order to the pipeline when HttpServerCodec is used (#9386)
Motivation:

- Correctly place encoder before decoder
- Add unit test

clients, Origin header field may be sent if it makes sense in the context of those clients.

Modification:
