RFC Allow full bridge configuration via sysfs

Right now, you can configure most bridge device parameters via sysfs. However, you cannot either:
- add or remove bridge interfaces
- add or remove physical interfaces from a bridge

The attached patch set rectifies this. With this patch set, brctl (theoretically) becomes completely optional, much like ifenslave is now for bonding. (In fact, the idea for this patch, and the syntax used herein, is inspired by the sysfs bonding configuration.)

Patchset is against net-next-2.6, but should apply to anything reasonably recent with minimal fuzz.

Add a 'bridging_masters' file in sysfs under class/net Add a 'interfaces' file to the bridge device configuration in sysfs
