The change to "optimize" the template by not rebuilding the reply
message when the original header channels was null was incorrect.
We need to null out those headers if they were originally null.
Issue: SPR-15991
Provide a mechanism to override the configured send and receive
timeouts in the GenericMessagingTemplate.
- overload `doReceive()` to take a receive timeout argument
- for `sendAndReceive()` methods examine message headers for these
timeout values
- remove headers to avoid propagation
- avoid the unconditional rebuild of the reply message if the
original headers weren't present
- also remove headers from simple `send()` operations
- change javadocs for the setters to indicate they are now defaults
- add properties to allow the user to override the header names used
- change `TemporaryReplyChannel` to use `send` arg and change to static
- add package-protected ctor to avoid the compiler creating a
synthetic constructor for access

This commit introduces 2 new @Nullable and @NonNullApi
annotations that leverage JSR 305 (dormant but available via
Findbugs jsr305 dependency and already used by libraries
like OkHttp) meta-annotations to specify explicitly
null-safety of Spring Framework parameters and return values.
In order to avoid adding too much annotations, the
default is set at package level with @NonNullApi and
@Nullable annotations are added when needed at parameter or
return value level. These annotations are intended to be used
on Spring Framework itself but also by other Spring projects.
@Nullable annotations have been introduced based on Javadoc
and search of patterns like "return null;". It is expected that
nullability of Spring Framework API will be polished with
complementary commits.
In practice, this will make the whole Spring Framework API
null-safe for Kotlin projects (when KT-10942 will be fixed)
since Kotlin will be able to leverage these annotations to
know if a parameter or a return value is nullable or not. But
this is also useful for Java developers as well since IntelliJ
IDEA, for example, also understands these annotations to
generate warnings when unsafe nullable usages are detected.

Currently the BOM versions are:
* reactor-core 3.0.6.BUILD-SNAPSHOT
* reactor-netty 0.6.2.BUILD-SNAPSHOT
This commit fixes as well a few deprecations in reactor-core.
This commit *adds* the "intercepted" headers to the ClientHttpRequest,
as opposed to replacing them, which is what happened before this commit.
Issue: SPR-15166
When connecting with a ReconnectStrategy we can only report the outcome
of the first connect to the ListenableFuture<Void> return value.
Failures for all subsequent attempts to reconnect however must be
channeled to TcpConnectHandler#afterConnectFailure which is used in
the STOMP broker relay for example to publish
BroadcastAvailability(true/false) events.
When decoding STOMP messages unread portions of a given input ByteBuf
must be kept until more input is received and the next complete STOMP
frame can be parsed.
In Reactor Net 2.x this was handled for us through the "remainder"
field in NettyChannelHandlerBridge. The Reactor Netty 0.6 upgrade
however applied only a simple map operator on the input ByteBuf
after which the buffer is relased.
This commit replaces the use of a simple map operator for decoding
and installs a ByteToMessageDecoder in the Netty channel pipeline
which has a built-in ability to preserve and merge unread input into
subsequent input buffers.
Create a ReactorNettyCodec to hold the decoding and encoding function
and consumer along with a package-private sub-class that delegates to
StompDecoder and StompEncoder.
