Merge r1855646, r1855748 from trunk:

mod_proxy/ssl: cleanup per-request SSL configuration for recycled proxy conns.

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.

* Solve a chicken and egg problem here:

 We need to have sslconn->dc set correctly when we want to

 init sslconn, but we need to allocate memory for it first.

PR 63256.
