This changeset introduces the new libnetmap library for writing
netmap applications.
Before libnetmap, applications could either use the kernel API
directly (e.g. NIOCREGIF/NIOCCTRL) or the simple header-only-library
netmap_user.h (e.g. nm_open(), nm_close(), nm_mmap() etc.)
The new library offers more functionalities than netmap_user.h:
- Support for complex netmap options, such as external memory
allocators or per-buffer offsets. This opens the way to future
extensions.
- More flexibility in the netmap port bind options, such as
non-numeric names for pipes, or the ability to specify the netmap
allocator that must be used for a given port.
- Automatic tracking of the netmap memory regions in use across the
open ports.
At the moment there is no man page, but the libnetmap.h header file
has in-depth documentation.

Coverity flagged the scaling by sizeof(uzd). That is the type
of the pointer, so the scaling was already done by pointer arithmetic.
However, this was also passing a stack frame pointer to kvm_read,
so it was doubly wrong.
Move ZDOM_GET into the !_KERNEL section and use it in libmemstat.

In parallel builds, this should allow sqlite to start building earlier and

optimizing the massive sqlite3.c file since the build of libsqlite3 is

performs are protected by an exclusive lock, even for statically linked

temporarily disabled in r364263.
Meanwhile upstream has also used the _LIBUNWIND_USE_FRAME_HEADER_CACHE

compile-time command line flag.
While here, reformat the CFLAGS lines a little bit.

warnings anymore for compiler-rt's atomic.c. This occurred because the
IS_LOCK_FREE_8 macro was not correctly defined to 0 for mips, and this
caused the compiler to emit a runtime call to __atomic_is_lock_free(),

sys/ccompile.h no longer uses #pragma ident, so we no longer need to worry
about unknown pragmas.
I fixed one WARNS issue in r363409 by annotating be_is_auto_snapshot_name's
lbh parameter __unused, then upstreamed the following changes to OpenZFS
that rode in with the merge:
- zfs_path_to_zhandle now takes a const char *path rather than a char *path,
since it won't be mutating the string it receives and I had no reason to
believe it will need to in the future. [OpenZFS PR #10605]
- Annotated some unused parameters on definitions inlined into headers as
such. [OpenZFS PR #10606]
We need to define the LUA_FLOAT_INT64 macro even if we don't use it (copied
from stand/luaconf.h). While touching luaconf.h.dist also sync it with the
the 5.3.5 release version (matches the one in lib/liblua).

In most cases this simply builds the file from lib/libc for missing

There have been several mentions on our mailing lists about missing
atomic functions in our system libraries (e.g. __atomic_load_8 and
friends), and recently I saw __bswapdi2 and __bswapsi2 mentioned too.
To address this, add implementations for the functions from compiler-rt
to the system compiler support libraries, e.g. libcompiler_rt.a and and
libgcc_s.so.
This also needs a small fixup in compiler-rt's atomic.c, to ensure that
32-bit mips can build correctly.
Bump __FreeBSD_version to make it easier for port maintainers to detect

The primary benefit is maintaining a completely shared
code base with the community allowing FreeBSD to receive
new features sooner and with less effort.
I would advise against doing 'zpool upgrade'
or creating indispensable pools using new
features until this change has had a month+
to soak.
Work on merging FreeBSD support in to what was
at the time "ZFS on Linux" began in August 2018.
I first publicly proposed transitioning FreeBSD
to (new) OpenZFS on December 18th, 2018. FreeBSD
support in OpenZFS was finally completed in December
2019. A CFT for downstreaming OpenZFS support in
to FreeBSD was first issued on July 8th. All issues
that were reported have been addressed or, for
a couple of less critical matters there are
pull requests in progress with OpenZFS. iXsystems
has tested and dogfooded extensively internally.
The TrueNAS 12 release is based on OpenZFS with
some additional features that have not yet made
it upstream.
Improvements include:
project quotas, encrypted datasets,
allocation classes, vectorized raidz,
vectorized checksums, various command line
improvements, zstd compression.
Thanks to those who have helped along the way:
Ryan Moeller, Allan Jude, Zack Welch, and many
others.

This is a change in preparation for stopping to use lorder.sh (D26044) and
instead assume that we have a linker newer than ~1990. Without lorder.sh
duplicates end up being passed to the linker when building .so files and this
can result in duplicate symbol definition errors.
There is one minor change: libcompiler_rt.a will no longer provide
gcc_personality_v0 and instead we now only have it in libgcc_eh.a/libgcc_s.so.
This matches GCC's behaviour.

Switch the latter to 80P80 for all the macros and comments refering

The only place we leave as 80p80 is the ifconfig command line arguments
as we spell them all in lower case.
Ideally we would use 80+80 for any interactions with the user and
80P80 for anything internal but let us not confuse parsers and
hence avoid the '+' in either case.

flua does have some specific bits that will include luaconf.h, but the
definition of LUA_USE_DLOPEN for those won't matter. This belongs in liblua
instead.
To expand on my previous commit, which was a little sparse with details,
it's not really safe to allow LUA_USE_DLOPEN with host lib paths being used.
The host system could have an entirely different lua version and this could
cause us to crash and burn.
If we want to revive this later, we need to make sure to define c module
paths inside OBJDIR that are compiled against whatever version we've
bootstrapped.

libifconfig_sfp.h provides an API in libifconfig for querying SFP module
properties, operational status, and vendor strings, as well as descriptions
of the various fields, string conversions, and other useful helpers for
implementing user interfaces.
SFP module status is obtained by reading registers via an I2C interface.
Descriptions of these registers and the values therein have been collected
in a Lua table which is used to generate all the boilerplace C headers and
source files for accessing these values, their names, and descriptions.
The generated code is fully commented and readable.
This is the first use of libifconfig in ifconfig itself. For now, the
scope remains very limited. Over time, more of ifconfig will be replaced
with libifconfig.
Some minor changes to the formatting of ifconfig output have been made:
- Module memory hex dumps are indented one extra space as a result of using
hexdump(3) instead of a bespoke hex dump function.
- Media descriptions have an added two-character short-name in parenthesis.
- QSFP modules were incorrectly displaying TX bias current as power. Now
TX channels display bias current, and this change has been made for both
SFP and QSFP modules for consistency.
A Lua binding for libifconfig including this functionality is implemented
but has not been included in this commit. The plan is for it to be
committed after dynamic module loading has been enabled in flua.
