     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.

It helps both code readability where stages are initilized and potential

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).

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).

Since the forwarding of 100-continue (end to end) in r1836588, we depended on
reading all of the requested HUGE_STRING_LEN bytes to avoid the flushes, but
this is a bit fragile.

This commit introduces the new stream_reqbody_read() function which will try a
nonblocking read first and, if it fails with EAGAIN, will flush on the backend
side before blocking for the next client side read.

We can then use it in stream_reqbody_{chunked,cl}() to flush client forwarded
data only when necessary. This both allows "optimal" flushing and simplifies
code (note that spool_reqbody_cl() also makes use of the new function but not
its nonblocking/flush functionality, thus only for consistency with the two
others, simplification and common error handling).

Also, since proxy_http_req_t::flushall/subprocess_env::proxy-flushall are now
meaningless (and unused) on the backend side, they are renamed respectively to
prefetch_nonblocking/proxy-prefetch-nonblocking, and solely determine whether
to prefetch in nonblocking mode or not. These flags were trunk only and may
not be really useful if we decided to prefetch in nonblocking mode in any case,
but for 2.4.x the opt-in looks wise.
