WIP audio in server

[Jeremy Whiting]

Hey all,

I'm implementing moving audio from the modules to the server (and
modules will send audio data to the server on a unix socket). I've got
the socket creation, and seem to have the ability to connect to the
socket in the modules but it's hanging here when I try to run spd-say
hello. Also I'm getting this in my speech-dispatcher.log as if it's
trying to open a second audio connection from sd_espeak for some
reason when it hangs (and no log output after this):

[Thu Jul 30 15:03:15 2015 : 829380] speechd:     Adding audio
connection on socket 4
[Thu Jul 30 15:03:29 2015 : 105629] speechd:    Adding module on fd 28
[Thu Jul 30 15:03:29 2015 : 105654] speechd:     Adding audio
connection on socket 4

I'm probably doing something obviously wrong, but can't seem to see
what at the moment though I've been beating my head against it for a
while and debugging. Can you see anything obvious in my changes?

thanks,
Jeremy
