websocket client library
This introduce 2 files for creating client
of websockets x-afb-json1:
- afb-wsj1.c
- afb-ws-client.c
The file afb-wsj1.c implements the protocol
x-afb-json1 on top of afb-ws.c.
It could be used to rewrite afb-ws-json1.
The file afb-ws-client.c implements a
light version of the websocket handshaking
to open a afb-wsj1 based on an uri.
