b5d787d93b libnv: fix memory leaks
nvpair_create_stringv: free the temporary string; this fix affects
nvlist_add_stringf() and nvlist_add_stringv().

nvpair_remove_nvlist_array (NV_TYPE_NVLIST_ARRAY case): free the chain
of nvpairs (as resetting it prevents nvlist_destroy() from freeing it).
Note: freeing the chain in nvlist_destroy() is not sufficient, because
it would still leak through nvlist_take_nvlist_array().  This affects
all nvlist_*_nvlist_array() use

032f0fbbb6 Allow bootstrapping libnv on macOS and Linux
MacOS/Linux do not define struct cmsgcred but we need to bootstrap libnv
when building on non-FreeBSD systems. Since they are not used during
bootstrap we can just omit these two functions there.

991666adc7 Ensure that libnv can be used when kern.trap_enotcap=1.
libnv used fcntl(fd, F_GETFL) to test whether fd is a valid file
descriptor.  Aside from being racy, this check requires CAP_FCNTL
rights on fd.  Instead, use fcntl(fd, F_GETFD), which does not require
any capability rights.

Also remove some redundant fd_is_valid() checks to avoid extra system
calls; in many cases we were performing this check immediately before
dup()ing the descriptor.

50a2c22918 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.

63889bbde0 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.

3cafc9a654 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/.

5e53a4f90f lib: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

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.

430f7286a5 Merge ^/user/ngie/release-pkg-fix-tests to unbreak how test files are installed
after r298107

Summary of changes:

- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
  namespacing is kept with FILES appropriately, and that this shouldn't need
  to be repeated if the namespace changes -- only the definition of PACKAGE
  needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
  `tests`. In the event we get to the point where things can be split up
  enough in the base system, it would make more sense to group the tests
  with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
  previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
  bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
  ${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
  and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)

Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.

347a39b4a6 Add support for the arrays in nvlist library.
- Add
  nvlist_{add,get,take,move,exists,free}_{number,bool,string,nvlist,
  descriptor} functions.
- Add support for (un)packing arrays.
- Add the nvl_array_next field to the nvlist structure.
  If an array is added by the nvlist_{move,add}_nvlist_array function
  this field will contains next element in the array.
- Add the nitems field to the nvpair and nvpair_header structure.
  This field contains number of elements in the array.
- Add special flag (NV_FLAG_IN_ARRAY) which is set if nvlist is a part of
  an array.
- Add special type (NV_TYPE_NVLIST_ARRAY_NEXT).This type is used only
  on packing/unpacking.
- Add new API for traversing arrays (nvlist_get_array_next).
- Add the nvlist_get_pararr function which combines the
  nvlist_get_array_next and nvlist_get_parent functions. If nvlist is in
  the array it will return next element from array. If nvlist is last
  element in array or it isn't in array it will return his
  container (parent). This function should simplify traveling over nvlist.
- Add tests for new features.
- Add documentation for new functions.
- Add my copyright.
- Regenerate the sys/cddl/compat/opensolaris/sys/nvpair.h file.
