[PATCH v3 0/4] Additional parameters for qemu_img map

[Eyal Moscovici]

Hi,

The following series adds two parameters to qemu-img map:
1. start-offset: mapping starting offset.
2. max-length: the length of the mapping.

These parameters proved useful when mapping large disk spread across
long store file chains. It allows us to bound the execution time of each
qemu-img map execution as well as recover from failed mapping
operations. In addition the map operation can divided to
multiple independent tasks.

V3 changes:
1. Add cvtnum_full and made cvtnum a wrapper function.
2. Keep the original boundaries checks.
3. Tone down error messages.

V2 changes:
1. Add error reporting to cvtnum.
2. Add image length validation in img_map.
3. Rebase over QEMU 5.0.

  qemu_img: add cvtnum_full to print error reports
