[Qemu-devel] [PATCH 1/3] Add a true or false option to the DEFINE_PROP_UUID macro.

[Venu Busireddy]

It may not always be desirable to have a random UUID stuffed into the
'_field' member. Add a new option '_default' to the macro, that will
allow the caller to specify if a random UUID needs be generated or not.

Also modified the instance where this macro is used.
