Guaranteed breakage upon upgrade isn't ideal.  I think there are three
possible better courses of action:

1) Have all the qemu package depend on all these small packages. This is
the least "Alpine-like" way of doing things, since it doesn't allow you
to avoid pulling in unnecessary things.

2) Have all the small packages be installed manually upon upgrade from
3.12 to  3.13 and leave it to the users to remove what they don't need.

3) Inform users in the release notes that manual intervention is
necessary.

I think we need a good write-up on the wiki of which packages are
required by which features. I didn't find one upstream, sadly...

As far as I've discovered:

* serial console:
	- qemu-chardev-spice

* graphics (using virtio driver):
	- qemu-hw-display-virtio-gpu
	- qemu-hw-display-virtio-gpu-pci (possibly only for i440FX?)
	- qemu-hw-display-virtio-vga (I didn't even get a BIOS POST
	without this.)
	- qemu-ui-opengl

* Spice:
	- qemu-ui-spice-core (not required if using VNC)

* USB redirection:
	- qemu-hw-usb-redirect (pretty self explanatory)
