+ fix use of partx for newer util-linux versions (LP: #1587971)
[Lars Kellogg-Stedman]
+ fix some issues in error path reporting
+ capture output of 'partx --help' as older versions
do not support that flag, and send output to stderr.
+ fix bug when growing partitions on disks > 2TB. (LP: #1259703)
+ run partx only on block devices (not files)
+ better --dry-run output for gpt disks, providing sgdisk command
line that would be used.
+ support sfdisk >= 2.26, and support gpt partitions with sfdisk
