[section:SignalHandler Signal handler requirements]

A signal handler must meet the requirements for a [link
asio.reference.Handler handler]. A value `h` of a signal handler class
should work correctly in the expression `h(ec, n)`, where `ec` is an lvalue of
type `const error_code` and `n` is an lvalue of type `const int`.
