The tap backend is already using qemu-bridge-helper to attach tap

This adds a "br" property support to the tap backend.

Stupid question ahead: how does -netdev bridge compare to -netdev tap
after this patch? Is there a case left where you must use -netdev bridge?
Or can we make -netdev bridge a synonym for "-netdev
tap,helper=/default/path/to/helper"?
I looked through history but I could not understand why "bridge" was
introduced in the first place as even there (a7c36ee4920ea) is an example of
-netdev tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0",id=hn0
so it was assumed even then that people might want tap on a specific bridge.
So my stupid question is - what do I have to do to get this accepted
(besides a note that it is 2.8+) or it is not interesting to anyone? :)
