Base class for the various backend implementations.

Implements callback registration functions and defines the main backend APIs.

Variable before_callback
Variable after_callback

function(Backend:void) Pike.__Backend.before_callback
function(Backend:void) Pike.__Backend.after_callback

Description

If set, these are called just before and after the backend waits for an event.

If an error is thrown from these callbacks then it is reported using master()->handle_error() - it doesn't interrupt the operation of the backend.
