v5: Add union fields in QemuUUID to help the alignment necessary for bswap, and
    assert. [Richard]
    Update the test case initializer syntax accordingly.

v4: Use memcpy instead of pointer type cast. [Richard]
    Keep parameter order consistent with libuuid. [Jeff]
    qemu_uuid_convert -> qemu_uuid_bswap. [Jeff]

v3: Negative tests. [Daniel]
    Update QemuUUID type from array to struct. [Markus]
    Add qemu_uuid_unparse_strdup.
    Add qemu_uuid_convert.
    Redirect configure obsoleted option message to stderr. [Jeff]
    vdi: uuid_convert -> qemu_uuid_convert.
    Fix commit message syntax errors in vpc patch. [Jeff]
    Further cleanup around qemu_uuid.

v2: Fix the endianness wrongness. [Jeff]
    Add tests/test-uuid.c. [Denial]
    Add r-b of Stefan Weil to the VDI patch.

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, as well as some duplicated sscanf, snprintf and g_strdup_printf
  around UUID_FMT, which can be replaced with UUID parse/unparse routines.

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.

A number of different places across the code base use CONFIG_UUID. Some
of them are soft dependency, some are not built if libuuid is not
available, some come with dummy fallback, some throws runtime error.

It is hard to maintain, and hard to reason for users.

Since UUID is a simple standard with only a small number of operations,
it is cleaner to have a central support in libqemuutil. This patch adds
qemu_uuid_* the functions so that all uuid users in the code base can
rely on. Except for qemu_uuid_generate which is new code, all other
functions are just copy from existing fallbacks from other files.

Note that qemu_uuid_parse is moved without updating the function
signature to use QemuUUID, to keep this patch simple.

This removes our dependency to libuuid, so that the driver can always be
built.

Similar to how we handled data plane configure options, --enable-vhdx
and --disable-vhdx are also changed to a nop with a message saying it's
obsolete.

The UUID operations we need from libuuid is fully supported by QEMU UUID
implementation. Use it, and remove the unused code.

Previously we conditionally generated footer->uuid, when libuuid was
available. Now that we have a built-in implementation, we can switch to
it.

The uuid generation doesn't return error, so update the function
signature and calling code accordingly.

libuuid and make --enable-uuid and --disable-uuid only print a message.

Update all qemu_uuid users as well, especially get rid of the duplicated
low level g_strdup_printf, sscanf and snprintf calls with QEMU UUID API.

Since qemu_uuid_parse is quite tangled with qemu_uuid, it's switching to
QemuUUID is done here too to keep everything in sync and avoid code
churn.

Nit: BE endian is redundant.  big-endian or just BE, please.

Wait, didn't you just tell me that you *couldn't* add this union because of the 
packed usage within some file?

But of course if you're going to do this, you should actually use these fields,

Here,

And then you don't need this assert.

I was just saying even with this union added, packed usage can still result in
unaligned QemuUUID allocation, in theory. That's why I said I could assert too.
(In practise the only qemu_uuid_bswap is putting QemuUUID in a packed struct,
but that is happily aligned.)

Using these fields here requires an extra cpu_to_be16s for no compelling
reason, so I refrained to.
