In order to enhance paymetheus UX we need a more deliberate shutdown process in dcrd.exe.

Action items:

  • Audit the code that all relevant subsystems are being shutdown and add code to handle this
  • Make RPC server always reply with status "shutting down" and a status qualifier indicating what is up and what is down. Upon RPC server stop command this must be the first thing that happens.

Add pipes for parent process IPC. (#311)
6c1aa07 
Rewrite startup/shutdown logic to simplify shutdown signaling.  All
cleanup is now run from deferred functions in the main function.

Add two new config options to set the read and write ends of a pair of
pipes.  This is used as a simple mechanism for a parent process to
communicate with, observe, and manage the lifetime of a child dcrd
process.  When the RX (read end) pipe is closed, clean shutdown
automatically begins.

Add a new flag --lifetimeevents to create and send lifetime event
notifications over the TX (write end) pipe during bringup and
shutdown.  This allows the parent process to observe which subsystems
are currently starting, running, and stopping.

Fixes #297.
Fixes #298.
