libnv: bump library version

Now that we version symbols we should bump the library major version.
While here use version FBSD_1.7 to match the current HEAD FreeBSD
namespace and remove extraneous 'All rights reserved' and incorrect
copyright statement.

namespace nv names, version libnv and libnvpair library symbols

libnv and libnvpair have aliased symbols, and as a result a single process which
dlopens a shared object that is dynamically linked to libnv and another to
libnvpair will wind up with a single set of resolved symbols for those in
conflict. A source file also cannot include both libnv and libnvpair headers
because of aliased identifiers. To resolve the situation, libnv types and
functions are namespaced via nv_namespace.h, and libnv symbols are
versioned. The msgio functions are not namespaced or exported as they are not
part of the external API.

libnv: Remove -I${SRCTOP}/sys

This should have been done as part of r336019 -- including ${SRCTOP}/sys is
not a good business model for something that's build in legacy/bootstrap
stages.

Beyond that, libnv seems to build quite alright as legacy, part of
buildworld, and standalone without. Axe it.

No longer install sys/nv.h and sys/cnv.h in lib/libnv/Makefile

Use tools/build/Makefile to install the headers into ${WORLDTMP}/legacy
instead. Compared to r336026 this has the minor advantage that it avoids
unncessary header installation when building the non-bootstrap libnv.

config(8): Fix broken ABI

r336019 introduced ${SRCTOP}/sys to the include paths in order to pull in a
new sys/{c,}nv.h. This is wrong, because the build tree's ABI isn't
guaranteed to match what's running on the host system.

Fix instead by removing -I${SRCTOP}/sys and installing the libnv headers
with `make -C lib/libnv includes`... this may or may not get re-worked in
the future so that a userland lib isn't installing includes from sys/.

Add HAS_TESTS to all Makefiles that are currently using the
`SUBDIR.${MK_TESTS}+= tests` idiom.

This is a follow up to r321912.

Convert traditional ${MK_TESTS} conditional idiom for including test
directories to SUBDIR.${MK_TESTS} idiom

This is being done to pave the way for future work (and homogenity) in

Remove the nvlist_.*[fv] functions.

Those functions are problematic, because there is no way to report
memory allocation problems without complicating the API, so we can
either abort or potentially return invalid results. None of which is
acceptable.

In most cases the caller knows the size of the name, so he can allocate
buffer on the stack and use snprintf(3) to prepare the name.

After some discussion the conclusion is to removed those functions,
which also simplifies the API.
