      *) SECURITY: CVE-2013-5704 (cve.mitre.org)
         core: HTTP trailers could be used to replace HTTP headers
         late during request processing, potentially undoing or
         otherwise confusing modules that examined or modified
         request headers earlier.  Adds "MergeTrailers" directive to restore
         legacy behavior.

Redo what was reverted in r1572627.
Don't reuse a SSL backend connection whose SNI differs. PR 55782.
This may happen when ProxyPreserveHost is on and the proxy-worker
handles connections to different Hosts.


Follows up r1572606.
MMN minor bump required by proxy_conn_rec change.


mod_proxy: follows up r1572630.
Don't reuse a SSL backend connection with no SNI for a request requiring SNI.


mod_proxy: Add comment and avoid ternary operator as condition (no functional change).
