qemu: Use a TAP device instead of slirp for networking
With this patch, a persistent TAP device is set up by poky-qemu-ifup, which is now run before qemu. The qemu command line now uses the device that was constructed (rather than the hard-coded tap0) and it is told not to run any networking scripts. When qemu shuts down, poky-qemu-ifdown removes the TAP device. sudo use - sudo is used to run poky-qemu-ifup. sudo is no longer used to run qemu, as qemu no longer needs privileges to set up networking. poky-qemu-ifdown is run without privileges, as you can remove a TAP device which you own.
