This is the first step toward fixing issue openwrt#33.

This still lacks some features:

- no support for "ignore" options
- no backward compatibility for option names
- no support for default interface options

Updates to babeld



This patchset:
- fixes openwrt#33 by generating a configuration file for babeld
- introduces a slightly different syntax for specfiying interfaces (backward-compatible)
- allows to use any option, as long as it's supported by babeld (i.e. valid options are not hardcoded in the init script anymore, all options are simply passed to babeld)

It is mostly backward-compatible, with a few caveats.

Thanks to Baptiste Jonglez.
