dc5f690b97ccdffa79fe7169bb26b0ebf06688bf qemu-img: Expose PreallocMode for resizing
Add a --preallocation command line option to qemu-img resize which can
be used to set the PreallocMode parameter of blk_truncate().
While touching this code, fix the fact that we did not handle errors
returned by blk_getlength().
