/// A protocol for binding and controlling the lifetime of a component instance
/// started using `ComponentRunner.Start()`. The component manager is the
/// intended direct client of this protocol.
///
/// When the controlled component instance terminates or becomes inaccessible
/// for any reason, the server closes the connection with an epitaph.
///
/// # Lifecycle
///
/// A component may exist in one of two states: `Started`, or `Stopped`. The
/// component is `Started` from the time `ComponentRunner.Start()` is called
/// until the ComponentRunner closes the ComponentController handle. The
/// component then transitions to `Stopped`.
///
/// Component manager uses ComponentController to terminate a component in two
/// steps:
///
/// 1.  Component manager calls `Stop()` to indicate that the ComponentRunner
///     should stop a component's execution and send the `OnStop` event.
/// 2.  If after some time the ComponentController is not closed, component
///     manager calls `Kill()` to indicate that the ComponentRunner must halt a
///     component's execution immediately, and then send the `OnStop` event.
///     The component manager may wait some period of time after calling `Kill()`
///     before sending `OnStop`, but makes no guarantees it will wait or for how long.
///
/// Component manager first waits for the ComponentController to close, and
/// then tears down the namespace it hosts for the stopped component. Component
/// manager may call `Kill()` without first having called `Stop()`.
///
/// Before stopping, a component can optionally use `OnEscrow` to store some
/// state in the framework, to receive those state again the next time it is
/// started.
///
/// When the component stops, the runner should send an `OnStop` event
/// instead of just closing the channel, to report the component's termination status
/// (see below) and (optionally) an exit code. Once the runner has sent `OnStop`
/// it is free to close [ComponentRunner]; the component framework will close
/// its end of the channel when it receives this event.
///
/// ## Legacy
///
/// Instead of sending `OnStop`, it is also legal for a runner to close the channel
/// with with an epitaph equal to the termination status, but this is a legacy method
/// for backward compatibility that's no longer recommended.
///
/// # Termination status
///
/// The termination status indicates the component's final disposition in the eyes of
/// the runner.
///
/// Note that termination status is _not_ synonymous with a component's exit code.
/// A component's exit code, which is optional for a runner to report, is an
/// integer that represents the program's own return code. For example, for ELF
/// components, it is the value returned by main(). The termination status is
/// the _runner_'s status code for the component's termination, which may capture
/// failure modes that occur in the context of the runner itself rather than the
/// program.
///
/// The following termination statuses may be sent by the server on error:
///
/// - `ZX_OK`: The component exited successfully, typically because the
///   component was asked to stop or it decided independently to exit.
/// - `INVALID_ARGUMENTS`:
///     * `start_info.resolved_url` is not supported by this
///       runner;
///     * `start_info` contains missing or invalid arguments.
/// - `INSTANCE_CANNOT_START`: The runner could not start the component.
///   For example, a critical part of the program could not be found or
///   loaded, or the referenced binary was invalid for this runner.
/// - `RESOURCE_UNAVAILABLE`: The component could not be launched due to
///   lack of resources.
/// - `INTERNAL`: An unexpected internal runner error was encountered.
/// - `INSTANCE_DIED`: The component instance was started but
///   subsequently terminated with an error.
/// - Other status codes (e.g. `ZX_ERR_PEER_CLOSED`) may indicate a failure
///   of the component runner itself. The component manager may respond to such
///   failures by terminating the component runner's job to ensure system
///   stability.
