Make cache_strqtok() return both the token and its unquoted argument (if any),
or an error if the parsing fails.

Cache-Control integer values (max-age, max-stale, ...) can then be parsed w/o
taking care of the (optional) quoting.

The SSL dir config of proxy/backend connections is stored in r->per_dir_config
but those connections have a lifetime independent of the requests they handle.

So we need to allow the external ssl_engine_set() function to reset mod_ssl's
dir config in between proxy requests, or the first sslconn->dc could be used
after free for the next requests.

mod_proxy can then reset/reinit the request config when recycling its backend
connections.

We need not remember each child's bucket number in SHM for restarts, for the
lifetime of the httpd main process the bucket number can be bound to the slot
number such that: bucket = slot % num_buckets.

This both simplifies the logic and helps children maintenance per bucket in
threaded MPMs, where previously perform_idle_server_maintenance() could create
or kill children processes for the buckets it was not in charge of.
