the hop-by-hop rules of rfc 2616 along with the entity response
rules. To make sure that they stay in sync; and to make it easier
to add (http) caching modules - this change moves them all into
one place (cache_util) and exposes a in-bound and out-bound
version to operate on the headers.
In short: we retire ap_cache_cacheable_hdrs_out() which was used
for both in- and out-put headers; and replace it by a single
ap_cache_cacheable_headers() which understands the hop-by-hop
rules. And then wrap this into an in- and out-put specific
ap_cache_cacheable_headers_in()/out() which we can teach things
about entity responses and so on.. The latter which will also
merge error and ensure content-type.
This API change bumps up the minor MM by one.

on each request in the request_config. During consecutive runs of
cache_generate_key_default during processing the request we restore it
from there as we might not be able to generate the same key again as
the ingredients used to compose the key might have changed and we constantly
must use a key that could be generated during the quick handler phase.

even if no expiration time is specified. Futhermore the query string will not
be used for key generation such that requests to the same URI path, but with
different query strings are mapped to the same cache entity. Turning this
setting to ON violates RFC 2616/13.9 and thus it is turned off by default.

hook, giving each cache backend the ability to make a better
decision as to how it will allocate the tasks of writing to the
cache and writing to the network. Previously the write to the
cache task needed to be complete before the same brigade was
written to the network, and this caused timing and memory issues
on large cached files. This fix replaces the previous fix for
PR39380.

* Add r->uri to the debug messages in the quick handler; makes debugging
easier.
* Always reset headers_in for lookup's, some modules make subrequests
and then rewrite the url. Having a conditional request at this point
is not what they expect (nor reasonable for them to handle).
* Don't store a per-request config on lookups; for the same reason.
* Return DECLINED when in lookup mode and ap_meets_conditions() indicated
we have the content but don't know if it's fresh or not. We have no idea
whether the backend will have a 404, a 304 or any other kind of a
response - so we have to assume we cannot handle the request.
* remove the unused "url" argument from the cache_create_entity() function
* Whitespace/comment fixups in mod_cache.h
