libbe: handle destroying/renaming temporary/bootonce boot environments When a temporary/bootonce boot environment is renamed, we need to also update the bootenv nvlist on-disk to reflect the new name. Additionally, when a temporary/bootonce boot environment is destroyed, we also need to clear out the on-disk state.

loader: zfs should support bootonce an nextboot bootonce feature is temporary, one time boot, activated by "bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag. By default, the bootonce setting is reset on attempt to boot and the next boot will use previously active BE. By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will be set permanently active. bootonce dataset name is recorded in boot pool labels, bootenv area. in case of nextboot, the nextboot_enable boolean variable is recorded in freebsd:nvstore nvlist, also stored in boot pool label bootenv area. On boot, the loader will process /boot/nextboot.conf if nextboot_enable is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf processing on next boot. bootonce and nextboot features are usable in both UEFI and BIOS boot. To use bootonce/nextboot features, the boot loader needs to be updated on disk; if loader.efi is stored on ESP, then ESP needs to be updated and for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated (gpart or other tools). At this time, only lua loader is updated. Sponsored by: Netflix, Klara Inc. Differential Revision: https://reviews.freebsd.org/D25512

Drop "All Rights Reserved" from all libbe/bectl files I sent out an e-mail on 2020/01/21 with a plan to do this to Kyle, Rob, and Wes; all parties have responded in the affirmative that it's OK to drop it from these files.

libbe(3): allow creation of arbitrary depth boot environments libbe currently only provides an API to create a recursive boot environment, without any formal support for intentionally limiting the depth. This changeset adds an API, be_create_depth, that may be used to arbitrarily restrict the depth of the new BE.

libbe(3): move altroot augmentation bits around a little bit We could perhaps have a method that does this given a dataset, but it's yet clear that we'll always want to bypass the altroot when we grab the mountpoint. For now, we'll refactor things a bit so we grab the altroot length when libbe is initialized and have a common method that does the necessary augmentation (replace with / if it's the root, return a pointer to later in the string if not). This will be used in some upcoming work to make be_mount work properly for deep BEs. MFC after: 1 week

libbe(3): Properly account for altroot when creating new BEs Previously we would blindly copy the 'mountpoint' property, which includes the altroot. The altroot needs to be snipped off prior to setting it on the new BE, though, or you'll end up with a new BE and a mountpoint of /mnt with altroot=/mnt MFC after: 3 days

libbe(3): Add be_mounted_at to check a mount point At a bare minimum, this function will return 0 if a BE is mounted at the given path or non-zero otherwise. If the optional 'details' nvlist is supplied, it is filled with an nvpair containing just the information about the BE mounted at the path. This nvpair is structured just as it is for be_get_bootenv_props, except limited to just the single mount point.

libbe(3): Disambiguate 'active' a little bit, add 'bootfs' - Rename 'active' to 'rootfs', which is used in other places to describe the currently booted (or about to be booted) BE. - Add 'bootfs', which indicates the next boot environment to be booted. This is pulled from the BOOTFS zpool property. - Go ahead and keep an open handle to the active zpool. We might need to enumerate datasets, get properties, and set properties (e.g. bootfs) throughout other libbe bits, and a single handle isn't overly expensive.
