[BusyBox] patch: add brctl/libbridge

[Nick Fedchik]

Hi All!

I made a raw and quick port of brctl and libbridge to BusyBox.
Patch (busybox-brctl.patch) availiable at
http://www.fedchik.org.ua/linux/busybox/

Currently no "brctld" availiable.
I has applied the patch and working last 2 weeks - all looks ok.

TODO:
- add enslaved interface indexes to "brctl show" and
"brctl showmacs brX"
