PR/58202: Malte Dehling: Don't link libzfs

adapt to ${CC_WNO_ADDRESS_OF_PACKED_MEMBER}

Simplify CWARNFLAGS to use ${CC_WNO_ADDRESS_OF_PACKED_MEMBER}
which works for both clang and gcc, and remove compiler-specific
equivalents.

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.

Use CPPFLAGS for -D and -I so that lint works.

Ignore address of packed-member for clang too

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.

FreeBSD has recently imported HAMMER1/2 support from DragonFlyBSD,
so why not in NetBSD as well.

Adapt "usr.sbin/fstyp/Makefile".

Sync with upstream r315983.

FreeBSD splits "zfs_context.h" into:
"lib/libzpool/common/sys/zfs_context.h" for user space
"uts/common/fs/zfs/sys/zfs_context.h" for kernel space

Do the same here, move and sync "sys/sys/zfs_context.h" to
"dist/lib/libzpool/common/sys/zfs_context.h" and
"dist/uts/common/fs/zfs/sys/zfs_context.h".

Change "Makefile.zfs" to search includes from "dist/lib"
before "dist/uts" so we get the right include file.

Adapt "usr.sbin/fstyp/Makefile" to get the right include file.

branches: 1.3.2;
merge a new version of the CDDL dtrace and ZFS code.
this changes the upstream vendor from OpenSolaris to FreeBSD,
and this version is based on FreeBSD svn r315983.

in addition to the 10 years of improvements from upstream,
this version also has these NetBSD-specific enhancements:
- dtrace FBT probes can now be placed in kernel modules.
- ZFS now supports mmap().

branches: 1.2.2;
Ignore pragma warnings with clang for the zfs code.

Restore backward compatibility of UFS2 with previous NetBSD releases by
disabling support in UFS2 for extended attributes (including ACLs).
Add a new variant of UFS2 called "UFS2ea" that does support extended attributes.
Add new fsck_ffs operations "-c ea" and "-c no-ea" to convert file systems
from UFS2 to UFS2ea and vice-versa (both of which delete all existing extended
attributes in the process).
