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]

This takes us 1 step closer to use Ant 1.9+ and remove Xerces and Xalan from the build chain.


Patch tested with the current doc build chain (Ant 1.6.5 + Xerces + Xalan) on the 2.4.x branch.
Even if actually we don't have any "<Foo>" and "Foo" directives, I've checked that the doc is built correctly in such a case.

     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.

Don't eat the EOS in ap_http_header_filter() if it comes in single brigade
with a full response to a HEAD request, otherwise mod_ratelimit will never
flush its pending data.

No, if we read more bytes than the C-L there is really something wrong in
our (or some) HTTP input filter.

Since stream_reqbody_cl() and stream_reqbody_chunked}() now have the same
structure, join them into a single stream_reqbody() function which is passed
the rb_method to handle only CL vs chunked cases differently.

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.

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).
