qemu-img: Saner printing of large file sizes
Disk sizes close to INT64_MAX cause overflow, for some pretty
ridiculous output:
$ ./nbdkit -U - memory size=$((2**63 - 512)) --run 'qemu-img info $nbd'
image: nbd+unix://?socket=/tmp/nbdkitHSAzNz/socket
file format: raw
virtual size: -8388607T (9223372036854775296 bytes)
disk size: unavailable
But there's no reason to have two separate implementations of integer
to human-readable abbreviation, where one has overflow and stops at
'T', while the other avoids overflow and goes all the way to 'E'. With
this patch, the output now claims 8EiB instead of -8388607T, which
really is the correct rounding of largest file size supported by qemu
(we could go 511 bytes larger if we used byte-accurate sizing instead
of rounding up to the next sector boundary, but that wouldn't change
the human-readable result).
Quite a few iotests need updates to expected output to match.
