Andy Green 42e8b189dc http cache policy 
This allows mounts to define the caching policy of the files inside them.

Support is added in lwsws for controlling it from the config files.

The api for serializing a mount struct opaquely is removed and lws_http_mount struct
made public... it was getting out of control trying to hide the options.
