CLI filtering

by Clod Patry for The Asterisk Project

Currently in Asterisk CLI, there's no way to debug real-time a specific channel. This causes a lot of problems, cause when you're having more then 10 channels on your system, it's really hard to track-down a specific channel. This project is to implement a channel-specific filter in the CLI. This is also to switch from the single verbose level to a multiple verbose level. Here's a link which contains more details: http://www.asterisk.org/node/48443
