      mod_ratelimit: Don't interfere with "chunked" encoding.

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.

Also, ap_http_header_filter() shouldn't eat the EOS for HEAD/no-body responses.
For instance mod_ratelimit depends on it since r1835168, but any next request
filter may as well to flush and/or bail out approprietely.

This fixes the regression introduced in 2.4.34 (r1835168).

ap_add_common_vars(): use apr_pstrmemdup().

This avoids a transient replacement/restore of '?' by '\0' in r->filename.


Use 'ap_request_has_body()' instead of duplicating its implemenation.

The logic in 'ap_request_has_body()' is:
    has_body = (!r->header_only
                && (r->kept_body
                    || apr_table_get(r->headers_in, "Transfer-Encoding")
                    || ( (cls = apr_table_get(r->headers_in, "Content-Length"))
                        && (apr_strtoff(&cl, cls, &estr, 10) == APR_SUCCESS)
                        && (!*estr)
                        && (cl > 0) )
                    )
                );
So the test is slighly different from the original code. (but this looks fine to me)

This also has the advantage to avoid a redundant call to 'apr_table_get()' and to improve readability.

While at it, move the test '!r->expecting_100' a few lines above because it is cheap.

      In 'ap_proxy_cookie_reverse_map', iterate over each token of the 'Set-Cookie' header field in order to avoid updating the wrong one.

This could happen if the header field has something like 'fakepath=foo;path=bar". In this case fakepath would be updated instead of path.

We don't need regex anymore in order to parse the field values and 'ap_proxy_strmatch_domain' and 'ap_proxy_strmatch_path' are now useless. (and should be axed IMHO)

      mod_ratelimit: fix behavior with proxied content

mod_ratelimit works by splitting data in "chunks"
to send to the client, sleeping a predefined amount
of time between them (200ms). So for example,
a rate-limit 40 value would correspond to a chunk size
of 8192 bytes, flushed to the client every 200ms.

The idea works fine when httpd directly serves the
content, since the filter will be called once with
a single bucket brigade. In the context of a proxied
content though the filter is likely to be called multiple
times, with a bucket brigade size that corresponds to
the maximum allowed buffer size. If this value is lower
or higher than the chunk size, the filter will not
properly rate limit the data going to the client.

This patch solves the problem with two fix:
1) do_sleep is now stored in the ctx context struct,
   so if the filter is invoked multiple times it
   will still sleep when needed. For example, say
   that the chunk_size is 8192 and the bucket brigate
   len is 10240: the filter will flush 8192 bytes
   on the first invocation, sleep 200ms, flush the
   remaining bytes and then finish. The next invocation
   will do the same, clearly not leading to the
   correct "sleeping pattern".
2) The example above highlights also another issue:
   mod_ratelimit should  flush only chunk_size bytes
   at the time (I am now excluding the burst calculation
   from the picture), and buffer between invocations
   unless the brigade contains EOS.

The change has been tested with various scenarios and
it looks working as expected, but of course more
feedback/testing is welcome.

The original patch was written by me and then Yann
refactored the code to be more precise and efficient,
basically transforming an axe in a wonderful Japanese
katana sword, so credits to him for this work.
