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> Wesley Shields <wxs at atarininja dot org>

- Add support for dumping current resource usage for processes via a new -r flag to procstat. - Add an -H flag to request information about threads rather than processes when dumping statistics. Currently it is only used for -r to display resource usage for individual threads instead of the entire process. Reviewed by: kib (older version without -H) MFC after: 1 month

Export the whole thread name in kinfo_proc kinfo_proc::ki_tdname is three characters shorter than thread::td_name. Add a ki_moretdname field for these three extra characters. Add the new field to kinfo_proc32, as well. Update all in-tree consumers to read the new field and assemble the full name, except for lldb's HostThreadFreeBSD.cpp, which I will handle separately.

void procstat_auxv(struct procstat *prstat, struct kinfo_proc *kipp);
- 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. Discussed with: rwatson
