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.

2a243b9539 Switch procstat from subcommand flags to verbs
- Use an enumerated value instead of separate flags for commands
- Look for a verb if no command flag is set
- Lookup the "xocontainer" value based on the command
- Document the new command verbs in the man-page

d57486e21c Updates to libprocstat(3) and procstat(1) to allow monitoring Capsicum
capability mode and capabilities.

Right now no attempt is made to unwrap capabilities when operating on
a crashdump, so further refinement is required.

0daf62d9f5 - Commit work from libprocstat project. These patches add support for runtime
file and processes information retrieval from the running kernel via sysctl
  in the form of new library, libprocstat.  The library also supports KVM backend
  for analyzing memory crash dumps.  Both procstat(1) and fstat(1) utilities have
  been modified to take advantage of the library (as the bonus point the fstat(1)
  utility no longer need superuser privileges to operate), and the procstat(1)
  utility is now able to display information from memory dumps as well.

  The newly introduced fuser(1) utility also uses this library and able to operate
  via sysctl and kvm backends.

  The library is by no means complete (e.g. KVM backend is missing vnode name
  resolution routines, and there're no manpages for the library itself) so I
  plan to improve it further.  I'm commiting it so it will get wider exposure
  and review.

  We won't be able to MFC this work as it relies on changes in HEAD, which
  was introduced some time ago, that break kernel ABI.  OTOH we may be able
  to merge the library with KVM backend if we really need it there.

254d03c508 Introduce a new sysctl process mib, kern.proc.groups which adds the
ability to retrieve the group list of each process.

Modify procstat's -s option to query this mib when the kinfo_proc
reports that the field has been truncated.  If the mib does not exist,
fall back to the truncated list.

5a246d2912 Add 'COMM' column to a few more output modes of procstat(1). The only
one it's missing from is the VM display, where there's really not room,
and the file output display is looking quite cramped.

3d91be41d1 Add procstat(1), a process inspection utility. This provides both some
of the missing functionality from procfs(4) and new functionality for
monitoring and debugging specific processes.  procstat(1) operates in
the following modes:

  -b  Display binary information for the process.
  -c  Display command line arguments for the process.
  -f  Display file descriptor information for the process.
  -k  Display the stacks of kernel threads in the process.
  -s  Display security credential information for the process.
  -t  Display thread information for the process.
  -v  Display virtual memory mappings for the process.

Further revision and modes are expected.
