Kevin pointed out that my recent change to byte-based instead of sector-based blk_write_zeroes() (commit 983a1600) makes life harder as long as bdrv_write_zeroes is still sector-based, and where the compiler doesn't flag any change in parameter types. Complete the conversion, by renaming things (so the compiler will help flag any future rebase conflicts), and making all write_zeroes operations nominally take bytes.
Definitely conflicts with Denis' qcow2_co_write_zeroes improvements series, and probably with Kevin's conversion of block jobs to BlockBackend. I can rebase if those land on the block branch first.
