86f222bbfe Do not use #warning to warn about missing implementation of dt_popc(),
but just have a comment that this is broken.

This is just a bandaid until somebody can fix this correctly.  The code
is just a broken as it was before r223262 - now buildworld just doesn't
fail.

1c3bf59584 Remove C constructs that are incompatible with C++ from various
OpenSolaris and ZFS header files.  These changes are sufficient
to allow a C++ program to use the libzfs library.

Note: The majority of these files already included 'extern "C"'
      declarations, so the intention of providing C++ compatibility
      already existed even if it wasn't provided.

cddl/compat/opensolaris/include/assert.h:
	Wrap our compatibility assert implementation in
	'extern "C"'.  Since this is a compatibility header
	I matched the Solaris style of doing this explicitly
	rather than rely on FreeBSD's __BEGIN/END_DECLS macro.

sys/cddl/compat/opensolaris/sys/kstat.h:
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/arc.h:
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/dsl_pool.h:
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/ddt.h:
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/spa.h:
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/zio.h:
	Rename parameters in function declarations that conflict
	with C++ keywords.  This was the solution preferred by
	members of the Illumos community.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/zfs_ioctl.h:
	In C, nested structures are visible in the global namespace,
	but in C++, they take on the namespace of the structure in
	which they are contained.  Flatten nested structure
	definitions within struct zfs_cmd so these structures are
	visible in the global namespace when compiled in both
	languages.

- Triple parity RAIDZ (RAIDZ3).

- Snapshot holds.
- zpool import -F. Allows to rewind corrupted pool to earlier

4f1f4356f3 Fix 'zfs allow' (maybe not only) returning:
cannot access dataset system/usr/home: Operation not supported

by including libzfs_impl.h. What libzfs_impl.h does is to redefine ioctl() to
be compatible with OpenSolaris. More specifically OpenSolaris returns ENOMEM
when buffer is too small and sets field zc_nvlist_dst_size to the size that
will be big enough for the data. In FreeBSD case ioctl() doesn't copy data
structure back in case of a failure. We work-around it in kernel and libzfs by
returning 0 from ioctl() and always checking if zc_nvlist_dst_size hasn't
changed. For this work-around to work in pyzfs we need this compatible ioctl()
which is implemented in libzfs_impl.h.

0f2bd1e89d Add libdtrace support for tracing userland programs.
Summary of changes:
* Implement a compatibility shim between Solaris libproc and our
libproc and remove several ifdefs because of this.
* Port the drti to FreeBSD.
* Implement the missing DOODAD sections
* Link with libproc and librtld_db
* Support for ustack, jstack and uregs (by sson@)
* Misc bugfixing

When writing the SUWN_dof section, we had to resort to building the ELF
file layout by "hand". This is the job of libelf, but our libelf doesn't
support this yet. When libelf is fixed, we can remove the code under
#ifdef BROKEN_LIBELF.
