direct sysctl calls.

  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.

WARNS fixes: mainly constness and avoid comparing signed with

2008-02-08T11:03:05+00:00

unsigned by making array indicies unsigned. Also note one or two
unused parameters.

Display per-thread command line in TDNAME field for -k and -t; if

2007-12-03T21:21:15+00:00

no per-thread name is available or the name is identical to the
process name, display "-" instead.  Very slightly shrink the COMM
entry to make a bit more room, although this doesn't help with
stack traces much.

Add procstat(1), a process inspection utility. This provides both some

2007-12-02T23:31:45+00:00

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.
