It would be nice to have an interface for elements interoperating with sound
servers.

Two methods seem particularly useful (for autoaudiosink for example, see bug
#343051):

 - sound_server_is_running()
   to check whether a server is running currently

 - sound_server_is_requested()
   to check whether the user explicitely requested to use a
   sound server (e.g. by setting environment variables)

It seems cleaner to me to do this with an interface (compared to using object
properties).

Proposed patch attached.

Not sure if it should be GstSoundServer or GstSoundServerControl or
GstSoundServerInfo or whatever, GstSoundServer seems most flexible though (and
is the shortest).

There might be a better name for the is_requested() method as well, but I can't
think of one right now.
