Richard Purdie 57196bc6e4 bitbake: prserv/serv: Improve process exit handling ...

The server shutdown is currenlty laggy and race prone. This patch:

* adds a waitpid so that no zombie server is left around if its not
  running in daemon mode.
* adds a quit "sentinal" using a pipe so that we're not sitting in
  a socket poll() until timeout in order just to quit.
* use a select() call to poll the socket and the pipe for a quit signal.

The net result of this change is that the prserv exits with the cooker server
and it does so immediately and doesn't wait for the select/poll calls to
timeout. This makes bitbake a lot more responsive for startup/shutdown and
doesn't cause UI timeout errors as often when prserv is used.
