d485c77f20 Remove #define _KERNEL hacks from libprocstat
Make sys/buf.h, sys/pipe.h, sys/fs/devfs/devfs*.h headers usable in
userspace, assuming that the consumer has an idea what it is for.
Unhide more material from sys/mount.h and sys/ufs/ufs/inode.h,
sys/ufs/ufs/ufsmount.h for consumption of userspace tools, with the
same caveat.

Remove unacceptable hack from usr.sbin/makefs which relied on sys/buf.h
being unusable in userspace, where it override struct buf with its own
definition.  Instead, provide struct m_buf and struct m_vnode and adapt
code to use local variants.

245bfd34da Deduplicate fsid comparisons
Comparing fsid_t objects requires internal knowledge of the fsid structure
and yet this is duplicated across a number of places in the code.

Simplify by creating a fsidcmp function (macro).

1de7b4b805 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.

591e89c89b 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.

f518456fdb Change file permissions for some setuid executables so they are "o+r".
The executable itself doesn't contain any privileged information.

An example of where this is useful is when makefs(8) is creating an image
that includes /sbin/shutdown. This can now be done without root privileges.

c8cf3f3d0e - 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.
