Unless I'm confused, we already have a lot of MIT-licensed code in the tree,
including much of the block layer, accel/tcg, the audio subsystem. Looking
at vl.c, it was put under the MIT license by Fabrice in 2003, so we've
been living with it as part of our licensing mix for a very long time already.
