[PATCH] add basic b4 config file

[Quentin Schulz <foss+yocto@0leil.net>]

From: Quentin Schulz <quentin.schulz@cherry.de>

b4[1] is a very nice tool for mail-based contribution. A config[2] file
exists to set up a few defaults. We can use it to set the To recipients
to always add, in our case the mailing list.

This shouldn't be necessary if we had a script that b4 prep --auto-to-cc
could call to find the mail address(es) to send to. Let's start without
it for now.

Support b4 for easier contribution workflow.

Note that this should be backportable as is to earlier releases.

Additionally, we may want to add:

send-prefixes = <insert release name>

in earlier release branches so that one doesn't even have to think about
adding the branch name when writing patches for older releases (added
bonus is that the maintainers would then know if someone has sent
patches developed on earlier releases instead of targeting master :) ).
