Rob N 3af63683fe cmd: add 'help' subcommand to zpool and zfs ... 'program help subcommand' is a reasonably common pattern for multifunction command-line programs. This commit adds support for that style to the zpool and zfs commands. When run as 'zpool help [<topic>]' or 'zfs help [<topic>]', executes the 'man' program on the PATH with the most likely manpage name for the requested topic: "zpool-<topic>" or "zfs-<topic>" for subcommands, or "zpool<topic>" or "zfs<topic>" for the "concepts" and "props" topics. If no topic is supplied, uses the top "zpool" or "zfs" pages.
