rwatson 88563131a0 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.

Testing, ideas, etc:	cognet, sam, Skip Ford <skip at menantico dot com>
