case by using iteration instead of recursion.

We have a relatively small recursion limit of
about 10 operations. This is a compilation
limit (a define). It can be hit if many expr
vars or function calls are concatenated.

The new optimization is very similar to the
existing one, which optimizes consecutive
concatenations in node2 of the tree. The new
one optimizes consecutive concatenations in
node 1.

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.
PR 37920.

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)
