We don't want the generator itself tagged as a generated file.

Multiple tools use @generated to identify generated files (for example,
in a review Phabricator will by default hide diffs in generated files).
Use the @generated tag in makeobjops.awk and vnode_if.awk as we've done
for other generated files.

METHOD and STATICMETHOD declarations; that code will be inserted
into the dispatch function before and after the method call.
Use this functionality and the TSLOG framework to record DEVICE_ATTACH
and DEVICE_PROBE entry/exit timestamps.
Mainly focus on files that use BSD 3-Clause license.
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.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Just place the default kobj_method inside the kobjop_desc structure.
There's no need to give these kobj_methods their own symbol. This shaves
off 10 KB of a GENERIC kernel binary.
These structures hold no information that is modified during runtime. By
marking this constant, we see approximately 600 symbols become
read-only (amd64 GENERIC). While there, also mark the kobj_method
structures generated by makeobjops.awk static. They are only referenced
by the kobjop_desc structures within the same file.
