[Qemu-block] [PATCH 0/7] UUID clean ups for 2.8

[Fam Zheng]

The facts how we use libuuid now are not particularly pleasant.

- VHDX driver depends on uuid, but is unconditionally checked in iotests 109.
  If it is not built, the test would fail, leaving no hint about that. In fact
  this even makes the feature implementation a bit ugly because it compromises
  the write protection on block 0 with image probing, silently.

- A few other libuuid users, in block/ and crypto/, use it as an optional
  dependency, and compromises certain functionalities if it is not available.

- On the other hand, there are already a few uuid function fallbacks in those
  callers.

So instead of making libuuid a hard requirement, let's simply move the
fallbacks to util and implement the random version of uuid generation, and be
done with it.
