libbe(3)/bectl(8): Standardize copyright headers - File names don't necessarily need to be repeated - Add SPDX tags - Add a missing copyright for Kyle Kneitinger in bectl.8, originally written by him in GSoC 2017; his standard copyright notice has been copied from other files within the same directory to remain consistent with how he clearly wished to portray it

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): 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. Submitted by: Rob Fairbanks <rob.fx907 gmail com> MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D18564

If the optional 'details' nvlist is supplied, it is filled with an nvpair containing just the information about the BE mounted at the path.
