              when using OpenSSL 1.1.1 and should not harm for versions before
              1.1.1.
              Without the patch for 1.1.1 a 0 byte read no longer results in
              EAGAIN but instead in APR_EOF which leads to HTTP/2 failures.
              For the changelog: Fix HTTP/2 failures when using OpenSSL 1.1.1.

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.)
