bsd.own.mk: rename to CC_WNO_ADDRESS_OF_PACKED_MEMBER

Provide a single variable
CC_WNO_ADDRESS_OF_PACKED_MEMBER
with options for both clang and gcc, to replace
CLANG_NO_ADDR_OF_PACKED_MEMBER
CC_NO_ADDR_OF_PACKED_MEMBER
GCC_NO_ADDR_OF_PACKED_MEMBER

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

add support for new GCC 9 warnings that may be too much to fix
right now. new address-of-packed-member and format-overflow
warnings have new GCC_NO_ADDR_OF_PACKED_MEMBER amd
GCC_NO_FORMAT_OVERFLOW variables to remove these warnings.

apply to a bunch of the tree. mostly, these are real bugs that
should be fixed, but in many cases, only by removing the 'packed'
attribute from some structure that doesn't really need it. (i
looked at many different ones, and while perhaps 60-80% were
already properly aligned, it wasn't clear to me that the uses
were always coming from sane data vs network alignment, so it
doesn't seem safe to remove packed without careful research for
each affect struct.) clang already warned (and was not erroring)
for many of these cases, but gcc picked up dozens more.

libnpf fix: link the library itself to libnv; libnpf users should not be
expected to assume this dependency.

branches: 1.17.2;
NPF: Major rework -- migrate NPF to the libnv library.
- This conversion significantly simplifies the code and moves NPF to
a binary serialisation format (replacing the XML-like format).
- Fix some memory/reference leaks and possibly use-after-free bugs.
- Bump NPF_VERSION as this change makes libnpf incompatible with the
previous versions. Also, different serialisation format means NPF
connection/config saving and loading is not compatible with the
previous versions either.

Thanks to christos@ for extra testing.

updates for GCC 6.4:

identd has aliasing violations, use -fno-strict-aliasing.

newfs_msdos's getbpbinfo() has missing {} issues.

sysctl's kern_cp_id() has missing {} issues.

Add libprop for static linking

add npf support.

Add forward/proxy support to identd(8).

Approved by christos.

new identd from Peter Postma.

don't need -lutil here

Add a -L (lie brazenly) flag, to demonstrate the perils of proof by
assertion^W^W^W^W^W^W^Wprovide admins with a means of providing a
standard host-wide identd response. From the man page:

The -L<user name> option instructs identd to lie brazenly
about the identity of the user in question. You didn't
really intend to trust my assertion about who I was any-
way, right?
This flag provides a way for a site to support services
requiring the ident protocol while providing a standard
answer to all ident queries. All queries to identd will
respond with a host type of `OTHER' and a username of
<user name>.

Upgrade to version 2.8.3.

merge lite-2 Makefiles (rcsids), and turn on WARNS for all of libexec.

WARNS?=1. RCS ids.

RCS id police.
