71ef5532d9 cam: Add event loop
Add a simple event loop to the cam application and use it in the main()
function, with an example of how to handle SIGINT to gracefully stop the
loop.

a22dcaaa78 cam: options: Don't implement move semantics for OptionsParser::Options
The compiler creates a move constructor automatically when none is
supplied, and it does the right thing by default in this case. Using
std::move() inside the function prevents the compiler from doing
return value optimization and actually hinders performances. Using
std::move() in the caller is unnecessary, the move constructor is used
automatically by the compiler.

For all these reasons remove the tentative optimization that resulted in
worse performances and worse code.
