qImmutable gets defined as QIDL(immutable) via qidl.h, and underneath
the covers it's all QIDL(). So we can change them easily if need be, and
still have the optional of using QIDL() for any current or new
annotations that get introduced. But QIDL() just ends up being
really noisey in practice, especially when a field has multiple
annotations, so I'd like to make that kind of usage the exceptional
case rather than the common one.
I went with qUppercase because it avoids all the previous issues with
using leading underscores, and it's reserved in terms of QEMU coding
guidelines as far as I can tell (we generally require leading capital
for typedefs and lowercase for variable names, and can work around
exceptions on a case by case basis by using QIDL() or some other name).
I also had it as q_* for a bit but that didn't seem much better on the
eyes we looking at converted structures.
