[Qemu-block] [PATCH v8 0/2] Add 'offset' and 'size' options

[Tomáš Golembiovský]

v7 -> v8:
- handling offset in raw_co_pwrite_zeroes and raw_co_pdiscard (+tests)
- offset and size are not allowed for SCSI generic devices
- raw_aio_ioctl: not allowed when offset or size is set
- raw_probe_blocksizes: return -ENOTSUP if offset is not multiple of block size
- raw_probe_geometry: return -ENOTSUP if offset or size is set

v6 -> v7:
- added tests

v5 -> v6:
- fix alignment check condition
- when size is not specified and device size is being used take offset
  into account

v4 -> v5:
- added two missing overflow checks
- comments from Eric Blake:
  - renamed 'fail' label to 'end'
  - fixed optional fields in JSON scheme
  - no punctuation at the end of error_setg() message
  - spaces around PRI* macros
  - using QEMU_IS_ALIGNED
  - typos

v3 -> v4:
- fix stupid compilation error and formatting issue

v2 -> v3:
- changed overflow check to make it clearer
- produce error instead of warning when size is not multiple of sector
  size

v1 -> v2:
- options were moved from 'file' driver into 'raw' driver as suggested
- added support for writing, reopen and truncate when possible

Tomáš Golembiovský (2):
  raw_bsd: add offset and size options
  qemu-iotests: test 'offset' and 'size' options in raw driver
