Summary:                    [patch] Automatic gain normalization in meetme
Description: 
Often during an audio conference, one of the participants has set a high
mic volume. Whenever he speaks, the other listeners hear his relatively
high volume. Similarly, someone has a low voice or has set a low mic
volume. Other participants have to strain to hear him.

This patch tries to overcome this problem by estimating the volume of the
participants and adjusting their gain. This adjustment is done every 2
seconds in the meetme app.

The patch adds a "g" flag to the meetme app. This option is tied up with
the "T" flag - talker detection. Both have to be on for this to work.

Changes are in apps/app_meetme.c, include/asterisk/dsp.h, main/dsp.c
