various fixes for ccl

and added some setup stuff for cl+ssl.

Still need to get the full chunked version of stream-write-sequence working for CCL (user agent currently gives "invalid chunked encoding" error if I try the full version with CCL now).

Also I need to push another commit which reverts @loliveira's "wait" edits to package-mp.lisp - that was giving error as well. ssh on gitlab.common-lisp.net seems to be down now, i'll push when I can. Meantime if you get this to work without error please let me know what aserve and queues you are using (I'm using your aserve with my latest changes which I just did a PR for, and queues-20170124-git which I think is the latest from quicklisp).
