We don't need to pass them in the protocol, brlapi__write can check the
coherency of andSize/orSize/regionSize immediately.

But I'm a bit reluctant to break the brlapi ABI now only to factorize
the size check.

Perhaps we should keep in a corner of brlapi.h or such the list of
things we would like to do on next ABI break.
