Andreas Kling 15afc88ffe AudioServer: Add a "main mix volume" and a simple program to get/set it
Give the mixer a main volume value (percent) that we scale all the
outgoing samples by (before clipping.)

Also add a simple "avol" program for querying and setting the volume:

- "avol" prints the current volume.
- "avol 200" sets the main mix volume to 200%
