libwebsockets/minimal-examples/http-server/minimal-http-server-generic-sessions/mount-origin/lwsgs.js
Andy Green f89aa401cc generic-sessions update 
Generic sessions has been overdue some love to align it with
the progress in the rest of lws.

1) Strict Content Security Policy
2) http2 compatibility
3) fixes and additions for use in a separate process via unix domain socket
4) work on ws and http proxying in lws
5) add minimal example
