Most subcommands got their own manpages (e.g. create). Some related commands grouped into a single manpage and symlinks created (e.g. set, get, and inherit). I did this when topics were either too short to warrant their own file or so interrelated that a user would want to refer between commands in the same file. Corrected .Sx internal references to .Xr cross refs; lots of .Sx references from when text was all in zfs.8 needed to be changed to .Xr zfs-$SUBCOMMAND 8 cross references. Divided subcommand list in zfs(8) into sections of related functionality. This required writing new descriptions for some commands. Preserved ".Os Linux", `.Os` macro parsing behavior differs between mandoc from the "BSD" mandoc package (available on Ubuntu) and man from Ubuntu's man-db package, which calls groff to format the manpages. Groff handles the `.Os` macro differently and wrongly, defaulting it to "BSD" in `/usr/share/groff/*/tmac/mdoc/doc-common`, instead of getting the default from `uname`. A future set of changes will introduce build-time preprocessing of manpages for platform-specific documentation and can insert the correct operating system name. Added SEE ALSO sections, the newly-divided zfs-*.8 subcommand man pages needed their own SEE ALSO sections pointing to related subcommands and, in some cases, documentation from other packages (e.g. zfs-share.8).
