Release-Specs

Dear releasing IoTlers,

in order to set concrete goals we want to reach for our next release (which we hopefully can finally tag at the end of this month), I set up a new repository: https://github.com/RIOT-OS/Release-Specs

It contains basically two directories: `specs` and `tests`. `specs` contains descriptions of the goals we want to achieve and how realization of these goals can be verified. `tests` (which is mostly empty for now) contains some scripts that automate these verifications (it's basically a code representation of the spec descriptions). The repository is meant to be continued for further releases.

Please feel free to comment on this or propose changes to the specs.

The main goal of the release is to introduce the full gnrc network as the new default network stack in RIOT.

Cheers, Oleg
