Since previous output filters may use ap_filter_should_yield() to determine
whether they should send more data (e.g. ap_request_core_filter), we need
to flush pending data from the core output filter first, and so on up the
chain.

Otherwise we may enter an infinite loop where ap_request_core_filter() does
nothing on ap_filter_output_pending() called from MPM event.

If a signal is received early when the MPM children start, signal_threads() may
be called concurrently with start_streads() thus before the latter (or its
underlying threads like the listener_thread) had a chance to create and init
the queues, mutexes, pollset and sockets array used by the former.

So move those initializations to a new setup_threads_runtime() function called
before start_threads(), where the pruntime pool is also created.

Since it may retain data and should run after other "request" filters, use
the last possible position for a "request" filter: AP_FTYPE_CONNECTION - 1.

By the time ap_http_header_filter() sends the header brigade and adds the
"CHUNK" filter, we need to garantee that the header went through all the
filters' stack, and more specifically above ap_http_chunk_filter() which
assumes that all it receives is content data.

Since rate_limit_filter() may retain the header brigade, make it run after
ap_http_chunk_filter(), just before AP_FTYPE_CONNECTION filters.

This fixes the regression introduced in 2.4.34 (r1835168).

When mod_proxy_http handles end-to-end "100 continue", it can't let
ap_http_filter() send its own interim response whenever the body is read.

req->expecting_100 internally (including to restore r->expecting appropriately).
