An L{IProcessProtocol} with a Deferred for events where the subprocess
starts and stops.
@ivar started: A L{Deferred} which fires with this protocol's
L{IProcessTransport} provider when it is connected to one.
@ivar stopped: A L{Deferred} which fires with the process output or a
failure if the process produces output on standard error.
@ivar output: A C{str} used to accumulate standard output.
@ivar errors: A C{str} used to accumulate standard error.

If the underlying C{sendmsg} call fails, L{send1msg} raises
L{socket.error} with its errno set to the underlying errno value.

Calling L{sendmsg} with SOL_SOCKET, SCM_RIGHTS, and a platform-endian
packed file descriptor number should send that file descriptor to a
different process, where it can be retrieved by using L{recv1msg}.
