Compare server and client version at the start of scrcpy

[npes87184]

We found that some people wrong use older server with newer client. For example, #613
To prevent this problem and let debug more easily. I add a patch to check this situation at the start of scrcpy.

It will show a warning when it finds version not matched.

If the client and server versions are different, the server may crash earlier on argument parsing ("expected n arguments"), so retrieving the version on the socket is too late.

A possible solution is that the client sends its version as the first parameter when executing app_process, and the server checks it.

Thank you for your suggestion, I create a commit at another branch in my repo, what about it?

The message looks a bit confusion about the role of server and client.

"The server version (" + clientVersion + ") does not match the client "
                    + "(" + BuildConfig.VERSION_NAME + ")"

Thank you for your help.
