Following on 3ebbfa2191 where the local
refCount was removed in favor of using the internal refCount of the
native data buffer, this commit ensures that LeakAwareDataBufferFactory
uses a PooledDataBufferFactory delegate by default.
There are also fixes for test issues with eager allocation uncovered by
these changes in StringDecoder and ResourceDecoder.
Use of Flux.just is problematic in that if the Flux is cancelled before
demand, the item may never be read, nor freed. Flux#just does not
even delegate cancellation signals.

Prior to this commit, handler methods in Spring MVC controllers were
not required to provide explicit path mappings via @RequestMapping (or
any of its specializations such as @GetMapping). Such handler methods
were effectively mapped to all paths. Consequently, developers may have
unwittingly mapped all requests to a single handler method.
This commit addresses this by enforcing that @RequestMapping methods
are mapped to an explicit path. Note, however, that this is enforced
after type-level and method-level @RequestMapping information has been
merged.
Developers wishing to map to all paths should now add an explicit path
mapping to "/**" or "**".

1. If the write Subscriber cancels with the item cached, release it.
2. If the write Publisher emits an error while the item is cached, when
the write Subscriber subscribes, release the cached item and emit the
error signal.

This commit improves CORS support by:
- Using CORS processing only for CORS-enabled endpoints
- Skipping CORS processing for same-origin requests
- Adding Vary headers for non-CORS requests
It introduces an AbstractHandlerMapping#hasCorsConfigurationSource
method in order to be able to check CORS endpoints efficiently.
