Pending input and output are now maintained separately in respectively
c->pending_input_filters and c->pending_output_filters, which improves
both performances and debug-ability.

Also, struct ap_filter_ring is made opaque, it's only used by util_filter
and this will allow us to later change it e.g. to a dual ring+apr_hash to
avoid quadratic search in ap_filter_prepare_brigade().

MMN major bumped due to the change in conn_rec (this is trunk only code
anyway for now).

Since [mpm]_note_child_killed uses the scoreboard's generation number for
child_status hook (MPM_CHILD_EXITED), we must initialize it early (i.e. in
[mpm]_note_child_started where MPM_CHILD_STARTED is set) to avoid race
conditions on restart (e.g. storm/loop of restarts) leading to AH00546.

Make the SSL filters chain return an error when the handshake fails with an

When a rewrite to proxy is configured in the server config, a check is made to make sure mod_proxy is active.  But the same is not done if a rewrite to proxy is configured in an .htaccess file. 

Basically this patch is the block of code from hook_uri2file that does the proxy check, copied to hook_fixup.

Patch provided by Michael Streeter [mstreeter1 gmail.com], slightly modified to use a new APLOGNO

There is no need to copy, strchr, strcmp and modify a string which is only used for TRACE2 logging.

Note that the code that looks similar a few lines below can not be optimized the same way because it is also returned in 'pmessage'.

- Remove the space in "character set" in the syntax of ProxyFtpDirCharset to avoid confusion (it is 1 parameter only)
- Use the correct syntax for the "default" values, so that they are parsed and correctly displayed in 'quickreference'
- Remove extra [] when directive's parameter are required

- correct the default password: apache-proxy@ instead of apache_proxy@.

'ap_unescape_urlencoded()' suggests that NULL can be passed to 'unescape_url()'.
So avoid a potential 'strchr(NULL, ...)' which is an undefined behavior.
