MFC r356676:

Unbound's config.h is manually maintained, using a ./configure produced
config.h as a guide. In practice contributed software maintains a copy
of config.h within its build directory tree containing its Makefile.
usr.sbin/unbound is the home for its config.h.

r314451:

Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones

The SRCTOP conversion simplifies pathing in make/displayed output.

Also, while here, change a hardcoded path to ar5523.bin.uu in the make target
with ${.ALLSRC} .

r314472:

Simplify/improve idioms in usr.sbin/ntp Makefiles

- Use SRCTOP-relative paths to other directories instead of
.CURDIR-relative ones. This simplifies pathing in make/displayed output.
- Also, use :H where possible/sensical to manipulate .CURDIR-relative
paths
- Remove superfluous bsd.own.mk .includes which are already handled via
src.opts.mk .includes

r314478:

Simplify idioms in Makefiles further

- Use SRCTOP-relative paths instead of .CURDIR-relative ones where possible
- Use :H to manipulate .CURDIR in areas instead of ..-relative paths.

MFH (r305381, r306457): upgrade to unbound 1.5.10 via 1.5.9

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Approved by: re (implicit)

Add to CFLAGS, rather than replacing.

This allows additional CFLAGS, as set in bsd.cpu.mk, to go through.

Remove unbound-contrl-setup since we use a local control socket which
does not require keys.

MFC after: 3 days
Relnotes: yes

Convert usr.sbin to LIBADD
Reduce overlinking

Rework privatelib/internallib

Make sure everything linking to a privatelib and/or an internallib does it directly
from the OBJDIR rather than DESTDIR.
Add src.libnames.mk so bsd.libnames.mk is not polluted by libraries not existsing
in final installation
Introduce the LD* variable which is what ld(1) is expecting (via LDADD) to link to
internal/privatelib
Directly link to the .so in case of private library to avoid having to complexify
LDFLAGS.
