7551d83c35 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

259c3ae367 Work around an issue with mksnap_ffs not working in chroot'ed environment.
The problem is that the statfs(2) system call used to determine the relevant
mount point returns path within real root in the f_mntonname, causing
nmount(2) system call to fail with ENOENT.

Use a bit of heuristics to skip over few starting path elements when it
happens until we hit an actual mount point.

For this to work properly the whole mount should be accessible within the
chroot, it's going to still fail if chroot only has access to a part of the
mounted fs.

d747431e06 - Move from mount(2) to nmount(2). This should allow to convert MNT_SNAPSHOT
flag from a mount flag to FS-specific flag.
- Simplify usage. Instead of 'mksnap_ffs /mnt/foo /mnt/foo/snap' allow to
  give only one argument: 'mksnap_ffs /mnt/foo/snap'. Old usage is also
  accepted for now.
- Add an example of how to mount a snapshot.

62316cd3c7 Check that the user running mksnap_ffs has permission to create and
remove a snapshot file from the directory in which they have requested
to have it made. If they do not have write permission in the directory
or the directory is sticky and not owned by the user, then they
will not be able to remove the snapshot when they are done with it.

af2849b505 Add the mksnap_ffs command to the sbin directory. This setuid root
program allows users in the operator group to take filesystem
snapshots. Its first use will be in support of `dump -L'.
