This is nice from a code organization POV, but it doesn't do all
that much from a code reviewer / author POV as I doubt anyone
will remember which header file the respective APIs/structures/
constants are in, without having to look it up each time.

It would make life easier if we had distinct namning conventions
for APIs/struct/contsants in the respective headers.

eg instead of  "bdrv_" have "bdrv_state_" and "bdrv_io_" as
the two naming conventions for -global-state.h and -io.h
respectively, nad only use the bare 'bdrv_' for -common.h

Yes, this would be major code churn, but I think it'd make
the code clearer to understand which will be a win over the
long term.

NB, I'm not suggesting doing a rename as part of this patch
though. Any rename would have to be separate, and likely
split over many patches to make it manageable.

Regards,
Daniel
