- When iterating snapshots with name only, e.g., "-o name -s name", libzfs uses simple snapshot iterator and results are displayed in alphabetic order. This PR adds support for faster version of createtxg sort by avoiding nvlist parsing for properties. Flags "-o name -s createtxg" will enable createtxg sort while using simple snapshot iterator. - Added support to read createtxg property directly from zfs handle for filesystem, volume and snapshot types instead of parsing nvlist.
