The transform_sector() function is not very clear in what it's doing
and confusing. The GRUB already has a function which is doing the same
thing in a very self explanatory way, i.e., grub_disk_to_native_sector().
So, it's much better to use self explanatory one than transform_sector().

It will be desirable in the future to allow having the read hook modify the
data passed back from a read function call on a disk or file. This adds that
infrastructure and has no impact on code flow for existing uses of the read
hook. Also changed is that now when the read hook callback is called it can
also indicate what error code should be sent back to the read caller.

The function grub_disk_get_size() is confusingly named because it actually
returns a sector count where the sectors are sized in the GRUB native sector
size. Rename to something more appropriate.
