Proposal of a new build system using waf

[Gustavo Sousa]

Hi guys,

Caio, Lucas and I have been working on a new build system for ardupilot based on waf.

I've raised a pull request as a "Request For Comments" so that we can use GitHub interface to post comments (on code or not) and also suggestions.

Your comments (posted there) will be very appreciated :)

Here is the link: https://github.com/diydrones/ardupilot/pull/3217

Best regards,

Gustavo Sousa
