Summary:                    [patch] [OpenSolaris] wav format produces garbage
files
Description: 
I was toying with changing the recording format for voicemail files on my
server.  The GSM format had been working fine to both record and playback
files.  However switching voicemail.conf to create wav files results in
garbage data.  The files do not play back at all on several platforms,
including the server that recorded it.

I also attempted to record wav audio using the Record() dialplan
application.  The same garbage files resulted.  Here is what the console
says when trying to playback one of the files:

[Jan 14 21:27:53] WARNING[14811]: app_playback.c:471 playback_exec:
ast_streamfile failed on SIP/F27564A6-8B0D-408E-00000028 for
/tmp/1263522240.57
[Jan 14 21:27:53] WARNING[14811]: format_wav.c:95 check_header: Does not
begin with RIFF
[Jan 14 21:27:53] WARNING[14811]: file.c:370 fn_wrapper: Unable to open
format wav

The size of the file produced varies approximately according to duration,
so some data is getting in there.

This does not seem to impact other formats.  Playback of known-good wav
files works fine so it only seems to be a problem writing the wav format.

I just uploaded a simple patch that will make setbuf run before the header
is written.
