Matthew Jordan 16fd65bb73 Improve disk writes for wav49 format ... Writing to a file in the wav49 format performs rather inefficiently. The procedure is approximately: (1) Write GSM frame to the end of the file (2) Seek to the end of the file (3) Seek to the header (4) Update the file size (5) Seek (again) to the end of the file (6) Repeat This pattern negates any attempt to use the stdio buffering setup in ast_writefile. It also results in many small writes that require a seek going to the disk each second which translates to poor disk performance on certain file systems, particularly when there are multiple wav49 files being written simultaneously.
