Log message:
Change BUILDLINK_DEPENDS.foo to BUILDLINK_API_DEPENDS.foo.

Change BUILDLINK_RECOMMENDED.foo to BUILDLINK_ABI_DEPENDS.foo.

As discussed on tech-pkg.

Log message:
Catch up to modern pkginstall framework: USE_PKGINSTALL has been dead
for a while now, and *_EXTRA_TMPL are generally not needed anymore.

Log message:
Removed the quotes around SUBST_MESSAGE.* where they were unnecessary.

Log message:
Ran pkglint --autofix over the complete pkgsrc-wip. This changed all
instances like MAKE_ENV+= VAR=${VAR} to the properly quoted form,
VAR=${VAR:Q}, or even VAR=${VAR:M*:Q} if necessary.

Manually reviewed the changes.

Log message:
Converted USE_GNU_TOOLS to USE_TOOLS.

Log message:
Removed trailing white-space.

Log message:
RCD_SCRIPTS_EXAMPLEDIR is no longer customizable.
And always is defined as share/examples/rc.d
which was the default before.
 
This rc.d scripts are not automatically added to PLISTs now also.
So add to each corresponding PLIST as required.
 
This was discussed on tech-pkg in late January and late April.

Not all of these packages have been tested.
 
Todo: remove the RCD_SCRIPTS_EXAMPLEDIR uses in MESSAGES and elsewhere
and remove the RCD_SCRIPTS_EXAMPLEDIR itself.

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
- Fix custom do-install to be more like default app install
