  *) mod_http2: when SSL renegotiation is inhibited and a 403 ErrorDocument is
     in play, the proper HTTP/2 stream reset did not trigger with H2_ERR_HTTP_1_1_REQUIRED.
     Fixed. [Michael Kaufmann] 

  *) mod_http2: new configuration directive: `H2Padding numbits` to control 
     padding of HTTP/2 payload frames. 'numbits' is a number from 0-8,
     controlling the range of padding bytes added to a frame. The actual number
     added is chosen randomly per frame. This applies to HEADERS, DATA and PUSH_PROMISE
     frames equally. The default continues to be 0, e.g. no padding. [Stefan Eissing] 
  
  *) mod_http2: ripping out all the h2_req_engine internal features now that mod_proxy_http2
     has no more need for it. Optional functions are still declared but no longer implemented.
     While previous mod_proxy_http2 will work with this, it is recommeneded to run the matching
     versions of both modules. [Stefan Eissing]
  
  *) mod_proxy_http2: changed mod_proxy_http2 implementation and fixed several bugs which
     resolve PR63170. The proxy module does now a single h2 request on the (reused)
     connection and returns. [Stefan Eissing]
  
  *) mod_http2/mod_proxy_http2: proxy_http2 checks correct master connection aborted status 
     to trigger immediate shutdown of backend connections. This is now always signalled
     by mod_http2 when the the session is being released. 
     proxy_http2 now only sends a PING frame to the backend when there is not already one
     in flight. [Stefan Eissing]

  *) mod_proxy_http2: fixed an issue where a proxy_http2 handler entered an infinite 
     loop when encountering certain errors on the backend connection. 
     See <https://bz.apache.org/bugzilla/show_bug.cgi?id=63170>. [Stefan Eissing]

  *) mod_http2: Configuration directives H2Push and H2Upgrade can now be specified per 
     Location/Directory, e.g. disabling PUSH for a specific set of resources. [Stefan Eissing]

  *) mod_http2: HEAD requests to some module such as mod_cgid caused the stream to
     terminate improperly and cause a HTTP/2 PROTOCOL_ERROR. 
     Fixes <https://github.com/icing/mod_h2/issues/167>. [Michael Kaufmann]

      mod_reqtimeout: factorize structs and code.

With a bit of macro magic, this is to avoid more code duplication when adding
new stages (next commit will add TLS/handshake timeouts handling in addition to
existing header and body ones).

No functional change here.


mod_reqtimeout: Allow to configure (TLS-)handshake timeouts.

The timeouts apply between the process_connection and pre_read_request hooks.
They are disabled by default for compatibily reasons.


mod_reqtimeout: follow up to r1853906: adjust hooks priorities comments.


mod_reqtimeout: follow up to r1853901: fix macro args.


mod_reqtimeout: follow up to r1853901: init stage name outside INIT_STAGE().

It helps both code readability where stages are initilized and potential
logging in the input filter (even if the stage is disabled).


mod_http2: fix for latest mod_reqtimeout change re handshake timeouts

      mod_cache_socache: avoid pool to heap reallocation.

Below some threshold, the previous code tried free (sub-)pooled memory ASAP by
moving small buffers (< capacity / 2) to a heap bucket. But this is not really
an optimization because first it requires at some point to allocate more than
the configured capacity, and second since this happens during response handling
the pool is about to be destroyed soon anymay.

This commit simply keeps the data in the subpool and uses a pool bucket for the
output brigade to take care of the lifetime until it's consumed (or not).

      MPMs unix: bind the bucket number of each child to its slot number

We need not remember each child's bucket number in SHM for restarts, for the
lifetime of the httpd main process the bucket number can be bound to the slot
number such that: bucket = slot % num_buckets.

This both simplifies the logic and helps children maintenance per bucket in
threaded MPMs, where previously perform_idle_server_maintenance() could create
or kill children processes for the buckets it was not in charge of.
