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 another scenario where depending on configuration the stream would
not get read.
    
    For custom commands we don't know whether the audio is coming from a
stream or not
    so we are going to have to read the data despite no channels.
