Return meaningful errors for brctl modification commands.

When datapaths and interfaces are modified, we now do more thorough
checks to see whether they will succeed or not.  When datapaths are
added, we now block until they are created, so that follow-on ioctl
calls to attach interfaces will immediately work.
