Summary:                    [patch] streamed moh breaks if nobody listen it
Description: 
If i have a moh class, which plays a network stream, and when no one
currently listening it, asterisk stops to receive data from player, 
then in a few minutes player stops reading network stream,
and then tcp connection dropeed from server side. Bad.

I did not find any player, which can always read network, even when no one
reads music from it.

I have looked what to patch, and decided, that asterisk's res_musiconhold
is the easiest way.

All we need, is to check for existence of 'listeners' not just before
reading music from player, but just after.
Look for code example in add.info.

With this patch, asterisk _always_ take music from player, and only then
decides what to do (waste away or play for somebody).

It's work fine in my production (1.6.0.3-rc1) for two month.

    Fix issue with streaming MOH failing if nobody is listening.

    When a music class is setup to actually provide music on hold
    from a stream we need to constantly read audio from it since it
    will constantly be providing audio. This is now done despite there
    being no channels listening to it.
