See the commit message of patch 2 for the background.
v2:
- Rebased. Commit f1d3cd79 changed many bdrv_* calls to blk_* calls.
This version tries to keep those conversions and use BlockBackend
where qemu.git master does or where it makes sense. Added patch 1 to
get blk_write_zeroes().
- Renamed s->out_backing as s->target_has_backing [Max]
- convert_iteration_sectors(): Limit n to BDRV_REQUEST_MAX_SECTORS
instead of INT_MAX [Max]
- convert_read(): Fixed sector number for image concatenation [Max]
- Fixed -S 0 for full allocation [Max, Peter]
- Leave has_zero_init = false instead of failing the conversion if
bdrv_make_zero() returns an error [Max]
- Set has_zero_init = true instead of 1 [Max]
- Don't ignore error returns in a final blk_write_compressed() [Max]
- Removed TODO comment after deciding that no change is needed
- Many added tests
