That would be really nice! A few comments below.

error.c isn't tied to a subsystem, it's really "qemu wide". If it
must reside in dir (ie. it can't be in the top dir), then I'd
suggest to put it in qmp.

qga/ has several files today, not only qga/main.c. I'd suggest
naming the directory qemu-ga and moving everything there, but it's
better to double check with Michael.

I'd move json-* files to qmp/.

Please, move qmp.c qmp-commands.hx to qmp/.
