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.

Usually, this context is not also EXEC_ON_READ so it's not fully processed, so
e.g cmd->path is not fluffed up yet because the closing tag
of the section is not read yet and ap_check_cmd_context()
doesn't work)

The code reverted attempted to restrict comparisons of the r->filename
to given DirectoryMatch blocks.

r->filename was already a non-directory entity at this point, because we
have already fallen out of the } while (thisinfo.filetype == APR_DIR);
block above.

The addition of r->d_is_directory was redundant.  That is what is always
returned by ap_get_core_module_config(r->per_dir_config).

Note modifying dir_config required an MMN major bump as this commit could
have realigned the offset of refs (had it been added to the end, this
would correspond to an mmn minor bump) and other fields packed into the
same bytes (this is undefined). Bump on revert to prevent unexpected crashes.
