Fixed issue with release.
And fixed SCOOP target compilation
Splitted ws server from httpd (i.e concurrent nino).
ws server code relies on httpd library.
Added a way to disable ssl support at compilation time for httpd library, and then ws server.
have specific no_ssl target to make it easier to test.
code cleaning, renaming.
fixed configuration files.
Always use WS_ prefix for web socket server classes (and common).
Changed the structure of the package, to follow similar logic for server and client.
Renamed using prefix WEB_SOCKET_ instead of WS_ .
Fixed compilation issue by using HTTP_STREAM_SOCKET for concurrency=none.
