Support more filesystems in fstat(1): now you can use fstat(1) to find out if files on msdosfs and cd9660 filestores are open. There was also a movement of some common things to a header, a small cleanup. PR: bin/16364 bin/7043 Submitted by: Peter Edwards <peter.edwards@openet-telecom.com>

lib: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified 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.

- 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

- Trim an unused and bogus Makefile for mount_smbfs. - Reconnect with some minor modifications, in particular now selsocket() internals are adapted to use sbintime units after recent'ish calloutng switch.
