Add interface NVME to devstat

This allows to list only NVMe devices in systat, iostat, vmstat, etc.

Fix asymmetry in devstat(9) calls by GEOM.

Before this GEOM passed bio pointer to transaction start, but not end.
It was irrelevant until devstat(9) got DTrace hooks, that appeared to
provide bio pointer on I/O completion, but not on submission.

devstat(9): Constify function parameters that can be const

No functional change.

When attempting to document the changed argument types in devstat.9, I
discovered the 20 year old manual page severe

devstat(9): Constify function parameters that can be const

No functional change.

When attempting to document the changed argument types in devstat.9, I
discovered the 20 year old manual page severely mismatched reality even
prior to my simple change. So I took a first cut pass cleaning that up to
match reality. I'm sure I've missed some things; the goal was just to leave
it better than when I started.

sys/sys: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I

sys/sys: further 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.

/* -> /*- for license, minor formatting changes

Add an XXX comment with a TODO item for next time we run a revision
on this API.

Make devstat_new_entry() take a const void * rather than const char *
argument, GEOM nodes are not identified by ascii string.
