Summary:                    [patch] streamplayer-like utility, but for anything
that comes out of a shell pipe
Description: 
streamplayer Asterisk utility can only be used for raw TCP streams.

I just adapted the utility to be useful with anything that comes from a
shell pipe and added it to my "pipe chain" for my streaming music-on-hold.
The utility takes input from stdin (in 2k blocks) and sends it to stdout
only if the write would not block. As explained in streamplayer, Asterisk
blocks writes to stdout when it does not need the MOH source, but streaming
mpg123/sox I use would still be outputting data.

This effectively gets rid of the error I had in my Asterisk at various
intervals depending on music-on-hold usage:

[Nov  8 09:31:17] NOTICE[24616] res_musiconhold.c: Request to schedule in
the past?!?!

John,

Thank you for the reply.

I was just thinking it may fix this "Request to schedule in the past?!?!"
error message. The message is associated with a temporary streaming pause
which resolves itself after some period of silence.  At least this is what
I see in my environment.

I also needed to pre-load the res_musiconhold.so in modules.conf otherwise
streaming would not work.  This one is related to res_timing_dahdi.so.  It
has to be loaded after the res_musiconhold.so for streaming to work.
