/**
* Takes collection of all filters/interceptors (either request/reader or response/writer) and

* mapping the name-bound annotation to the list of name-bound filters/interceptors.
*
* <p>Note, the name-bound filters/interceptors are removed from the original filters/interceptors
* collection. If non-null collection is passed in the postMatching parameter (applicable for
* filters only), this method also removes all the global postMatching filters from the original
* collection and adds them to the collection passed in the postMatching parameter.
*
* @param all Collection of all filters to be processed.
* @param applicationNameBindings collection of name binding annotations attached to the JAX-RS
* application.
* @return {@link MultivaluedMap} of all name-bound filters.
