- 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.

The goal of this operation is to NOT install header files which shouldn't
be used outside the nvlist library.

Since METAMODE has been added, sys.mk loads bsd.mkopt.mk which ends load loading
bsd.own.mk which then defines SHLIBDIR before all the Makefile.inc everywhere.
This makes /lib being populated again.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

Change the nvlist_recv() function to take additional argument that
specifies flags expected on the received nvlist. Receiving a nvlist with
different set of flags than the ones we expect might lead to undefined
behaviour, which might be potentially dangerous.
Update consumers of this and related functions and update the tests.

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.

nv_tests.cc managed to get two copies of several functions due to me
applying a patch in an unclean working tree. My kingdom for an

Make it possible to compile libnv in the kernel. Mostly this
involves wrapping functions that have a different signature in
the kernel and in userland (e.g. malloc()) in a macro that will
conditionally expand to the right API depending on whether the
code is being compiled for the kernel or not.
I have also #ifdef'ed out all of file descriptor-handling code,
as well as the unsafe varargs functions.

If an nvlist is set as a child of another nvlist with

Almost every operation performed on an nvlist was allocating a
new string to hold the key name. The nvlist_exists* family of
functions would always return false if they failed to allocate
the string. The rest of the functions would outright abort().
Fix the non-varargs variants of the functions to perform the
requested operations directly and the varargs versions to
allocate the string and call into the non-varargs versions.
The varargs versions are still broken and really can't be fixed,
so we might consider axing them entirely. However, now the non-
varargs functions are always safe to call.

Add an nvlist_set_error() function that can be used to force an
nvlist into the error state. This is useful both for writing
tests and for writing APIs that use nvlists internally.
