Prior to this commit, the `ProtobufHttpMessageConverter` would call
`outputMessage.getBody()` at the beginning of the `writeInternal`
method, thus writing HTTP headers. Since this method is trying to write
"x-protobuf" headers after that, protobuf support wasn't working
properly for the default "x-protobuf" media type.
Thanks Toshiaki Maki for the repro project!
Also fixed:
* improve `MockHttpOutputMessage` behavior to reproduce the read-only
state of HTTP headers once they've been written.
Issue: SPR-12229
Update PathMatchingResourcePatternResolver to include additional
protected methods that can be used by subclasses to optimize which
JARs are searched.
Issue: SPR-12231
Update SystemEnvironmentPropertySource to attempt optimized Map lookups
first, and only fall-back to the defensive SecurityManager safe-mode
if these fail.

This change defers determination of whether to invoke a message
converter in case of a null @ResponseBody value (or ResponseEntity with
a null body) until after the invocation of the ResponseBodyAdvice
chain. This allows a ResponseBodyAdvice to handle null values
potentially turning them into non-null value.s

This change extends the "websocket" scope to ApplicationContext events
published from StompSubProtocolHandler. This however will only work
with ApplicationEventMulticaster that multicasts events in the same
thread.
Issue: SPR-12172
Refine property source ordering so that sources already contained in the
environment remain before those added by @PropertySource annotations.
Issue: SPR-12198
Update JndiLocatorDelegate.isDefaultJndiEnvironmentAvailable() to
call `getEnvironment()` on the `InitialContext` in order to actually
trigger a NamingException if JNDI is not available.
Issue: SPR-12223
Update ConditionEvaluator to collect then sort Conditions before
evaluation. By annotating Conditions with @Ordered expensive operations
can be pushed to the back of the queue.
