Removed some out of date references and re-wrote
some sections. Added also a banner at the top of
the page to warn the users about stale content.
The next step is to improve the accept() related
documentation introducing the latest changes made
for event (and how awesome event is).

Couls also be <br> or <br/> but some (very) old clients don't like it.
httpd is not really consistent on it. (personnlaly <br> would be just fine for me but <br /> is the most commonly used form)

It allows a non httpd config file to be used as a marker directly in
httpd.conf without hiding logic in a script in front of apachectl
to do test -f and pass extra -D's.

This is something we've had in IBM's httpd distro for a little bit and
hadn't remembered to share. I've seen some questions/config files come
up in a few places lately that would benefit from this as an option.

It looks like this was the original intent. The provider
is not registered if apr-redis is missing.

It was previously failing to compile due to the dirconf being
hidden behind the #ifdef guard but not the routine module
code that used it.

Also changed terminology to be in sync with:
https://httpd.apache.org/docs/current/mod/directive-dict.html#Context

It was confusing in my opinion to read that ProxyPass wasn't supported
for the <Directory> context (since "directory" semantic is already
overloaded).

If other modules or libraries do not clear the OpenSSL error queue after
a failed operation, other code that relies on SSL_get_error() -- in
particular, code that deals with SSL_ERROR_WANT_READ/WRITE logic -- will
malfunction later on. To prevent this, explicitly clear the error queue
before calls like SSL_read/write/accept().

Function casts can cause hard-to-debug corruption issues if a
declaration is accidentally changed to be incompatible. Luckily, most of
the function casts for apr_table_do() calls are unnecessary. Remove
them, and adjust the signatures for helpers that weren't taking void* as
the first argument.

The remaining helper that requires a cast is http_filter.c's
form_header_field(), which is probably where many of these casts were
copy-pasted from. I have left it as-is: it has other direct callers
besides apr_table_do(), and it's already documented with warnings not to
change the function signature.
