Since rv is not used as an apr_status_t in the loop (it's logging is done by

More uses of ap_map_http_request_error() and AP_FILTER_ERROR so that we never
return an HTTP error status from a handler if some filter generated a response
already.
That is, from a handler, either ap_get_brigade() (an input filter) returned
AP_FILTER_ERROR and we must forward it to ap_die(), or ap_pass_brigade() (an
output filter) failed with any status and we must return AP_FILTER_ERROR in
any case for ap_die() to determine whether a response is needed or not.

input filter already did it while reading client's payload.
When an input filter returns AP_FILTER_ERROR, it has already called ap_die()
or at least already responded to the client.
Here we don't want to lose AP_FILTER_ERROR when returning from proxy handlers,
so we use ap_map_http_request_error() to forward any AP_FILTER_ERROR to
ap_die() which knows whether a response needs to be completed or not.
Before this commit, returning an HTTP error code in this case caused a double
response to be generated.
Depends on r1657881 to preserve r->status (for logging) when nothing is to be
done by ap_die() when handling AP_FILTER_ERROR.

The goal is to minimize the delay between this connection is considered alive
and the first bytes sent (should the client's link be slow or some input filter
retain the data).
This is a best effort to prevent the backend from closing (from under us) what
it thinks is an idle connection, hence to reduce to the minimum the unavoidable
local ap_proxy_is_socket_connected() vs remote keepalive race condition.
PR 56541.
Also, allow the new subprocess_env variable "proxy-flushall" to prevent any
buffering of the request body before it is forwarded to the backend.
When set, the prefetch is still done (although non-blocking), so we can still
determine Content-Length vs chunked vs spooled (depending on data available
with the header or while reading it), and then all brigades are flushed when
passed to the backend.
