After a chat with Yann and Eric on dev@, we agreed to
simplify the description.

committing for discussion purposes to trunk.  I have reopened PR60458 because
I am tempted to revert the entire thing, it was not really a release-to-release
regression because the reporter arbitrarily used a new 2.4 syntax and the semantics
were unclear.

It is useful to have global exceptions apply to per-location proxypass, but it totally
breaks the "fast" lookup part of it.

PR 60404 asks if the Timeout directive is related to
the amount of time to wait for the entire CGI script's
output or only the first byte received.
Checking in mod_cgi.c -> cgi_bucket_read shows a
apr_pollset_poll that should support the latter.

On #httpd-dev a user gave us some hints about what kind of
things would have been great to see in the HTTPProtocolOptions
directive's documentation, so I tried to apply them all.

I also added some examples taken from http_strict.t and tested
a bit. I didn't follow completely the complete change-set of
the HTTPProtocolOptions directive, so please review the change
and let me know if anything is wrong or missing.
