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?!?!

When I first saw this, I said, "Oh, cool.  A way to end the problem I had
been having in 1.6 with the "schedule in past" messages and moh eventually
(within 24 hours) stopping until a restart of asterisk.

After running with 1.8.1.1 for a while, I find that (at least on my
configuration) these messages have stopped, and moh lasts at least as long
as 1.8.1.1 has stayed up.

Has something fundamentally changed that would make something like this
unnecessary?
