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.

Prior to this commit only Propagation.NOT_SUPPORTED was supported for
disabling test-managed transactions via the `propagation` attribute of
`@Transactional`.
This commit allows users to specify Propagation.NOT_SUPPORTED or
Propagation.NEVER to disable test-managed transactions.
Closes gh-25909
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.

Prior to this commit, the EnclosingConfiguration mode used in
conjunction with @NestedTestConfiguration defaulted to INHERIT.
In other to allow development teams to change the default to OVERRIDE
(e.g., for compatibility with Spring Framework 5.0 through 5.2), this
commit introduces support for changing the default EnclosingConfiguration
mode globally via a JVM system property or via the SpringProperties
mechanism.
For example, the default may be changed to
EnclosingConfiguration.OVERRIDE by supplying the following JVM system
property via the command line.
-Dspring.test.enclosing.configuration=override
