*) mod_session_crypto: Add a SessionCryptoPassphraseFile directive so that
the administrator can hide the keys from the configuration. [Graham

*) mod_authn_socache: change directive name from AuthnCacheProvider

which this module provides cacheing (AuthnCacheProvideFor).

*) mod_proxy_http: Allocate the fake backend request from a child pool
of the backend connection, instead of misusing the pool of the frontend
request. Fixes a thread safety issue where buckets set aside in the
backend connection leak into other threads, and then disappear when
the frontend request is cleaned up, in turn causing corrupted buckets
to make other threads spin. [Graham Leggett]
