Upstream: optimized use of SSL contexts (ticket #1234).
To ensure optimal use of memory, SSL contexts for proxying are now
inherited from previous levels as long as relevant proxy_ssl_* directives
are not redefined.
Further, when no proxy_ssl_* directives are redefined in a server block,
we now preserve plcf->upstream.ssl in the "http" section configuration
to inherit it to all servers.
Similar changes made in uwsgi, grpc, and stream proxy.
