AudioServer: Add 'mute' member and methods to ClientAudioStream

When computing the 'output mix', the Mixer iterates over all client
audio streams and computes a 'mixed sample' taking into account mainly
the client's volume.

This new member and methods will allow us to ignore a muted client
when computing that mix.
