This patch adds scam's native protocol (aka ecm-client/ecm-server) to oscam (module-scam.c).
Main use case is connecting an oscam client to a scam server, as scam can only act as a scam ecm-server.
Connecting a scam-client to oscam is, of course, possible, too.
Note that a scam server will not reply if a cw cannot be found, so these requets will timeout.
There is currently no emm support. I do not know (yet) wheter the protocol supports them or not.
