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.
