Before this commit, ReadCompletionHandler delayed closing the channel
to allow an ongoing read to complete/fail so we can get a hold of the
associated DataBuffer and release it. This can be problematic since the
read take time to complete but even more importantly there was a race
condition where we didn't check if we've been disposed concurrently
while releasing the read flag.
This commit removes the delay and closes the channel immediately from
cancel() and that should in turn fail any ongoing read operation,
according to AsynchronousChannel, and the DataBuffer is released.
Further improvements include:
- combining the "reading" and "disposed" AtomicBoolean's into a
single "state" AtomicReference.
- an optimistic check to remain in READING mode and avoid state
switches when there is demand to continue reading.

This commit raises the minimum Coroutines version supported
to 1.4.0-M1 and above, and changes usages of awaitFirst() or
awaitFirstOrNull() to awaitSingle() or awaitSingleOrNull()
to fix gh-25007.
Closes gh-25914
Closes gh-25007
This commit adds support for Kotlin Coroutines suspending functions to
Spring MVC, by converting those to a Mono that can then be handled by
the asynchronous request processing feature.
It also optimizes Coroutines detection with the introduction of an
optimized KotlinDetector.isSuspendingFunction() method that does not
require kotlin-reflect.
Closes gh-23611
Now that there's a new JMH infrastructure for benchmarks and that
performance tests have been rewritten to use it, we should remove the
`PERFORMANCE` `TestGroup` to avoid introducing such tests in the future.
Closes gh-24830
We are passing custom values to the constructor of PooledByteBufAllocator in
tests in order to turn of caching. This is based on:
https://github.com/netty/netty/issues/5275#issuecomment-220547057
Netty 4.1.52 has significant changes in PooledByteBufAllocator:
https://github.com/netty/netty/pull/10267
After the changes, our current value for maxOrder=2, which results in
chunkSize=16K, causes an assert failure in PoolChunk where the runSize
exceeds the chunkSize.
Prior to this commit, the subtype suffix of a MIME type (see RFC 6839)
was not properly taken into account when checking compatibility between
MIME types.
For example, `"application/*"` was not considered as compatible with
`"application/vnd.io.spring+json"`.
This commit adds a new `MimeType#getSubtypeSuffix()` method to easily
extract the subtype suffix information. This method is then reused in
the `isCompatibleWith` implementation to better handle these cases.
Fixes gh-25350
