by SSLProxyMachineCertificate{File|Path}.

The certificates and keys loaded during configuration time got lost during
runtime if e.g. SSLProxyMachineCertificate{File|Path} was set on virtual host
level and there was an SSL directive at directory level, e.g. SSLRequire.

This fixes a regression likely introduced in r1740928 (backported in r1824187).

This fixes a crash during SSL renegotiation with OptRenegotiate set,
when client certificates are available from the original handshake
but were originally not verified and should get verified now.

mod_brotli, mod_deflate: Restore the separate handling of 304 Not Modified
responses allowing these modules to properly set or fix-up the response
headers such as Vary or ETag.

This change follows up on r1837056 that disabled that special handling and
thus resulted in a potential violation of RFC7232, 4.1:

   The server generating a 304 response MUST generate any of the following
   header fields that would have been sent in a 200 (OK) response to the
   same request: Cache-Control, Content-Location, Date, ETag, Expires,
   and Vary.)
