The changes piggyback JSON output support on top of channel programs (#6558). This way the JSON output support is targeted to scripting use cases and is easily maintainable since it really only touches one function (zfs_do_channel_program()). This patch ports Joyent's JSON nvlist library from illumos to enable easy JSON printing of channel program output nvlist. To keep the delta small I also took advantage of the fact that printing in zfs_do_channel_program() was almost always done before exiting the program.
