This is neither POSIX compliant nor what the implementation does.
This could be allowed by changing the value of TCSAFLUSH from 2 to 3,
but that doesn't seem worthwhile after 25+ years.

In certain situations lseek(2) will return successful although if no seek
was performed. This can happen when operating on devices that don't support
seeking (older tape drives) or when operating on changeable media devices
(such as DVD or Blu-ray devices) without a medium inserted.
Document this within the man page and update the POSIX compliance while here.

While this behaviour is harmless, it is really just an artifact of the
fact that the msgctl(2) implementation uses a user-visible structure as
part of the internal implementation, so it is not deliberate and these
pointers are not useful to userspace. Thus, NULL them out before
copying out, and remove references to them from the manual page.

The new function operates similarly to ifconfig_lagg_get_lagg_status and
likewise is accompanied by a function to free the bridge status data structure.
I have included in this patch the relocation of some strings describing STP
parameters and the PV2ID macro from ifconfig into net/if_bridgevar.h as they
are useful for consumers of libifconfig.

When the RISC-V port was initially committed to FreeBSD, GCC would
generate 64-bit long doubles, and the definitions in _fpmath.h reflected
that. This was changed to 128-bit in GCC later that year [1], but the
definitions were never updated, despite the documented workaround. This
causes printf(3) and friends to interpret only the low 64-bits of a long
double in ldtoa, thereby printing incorrect values.
Update the definitions now that both clang and GCC generate 128-bit long
doubles.

Some of the NetBSD contributed tests are gated behind the
__HAVE_LONG_DOUBLE flag. This flag seems to be defined only for
platforms whose long double is larger than their double. I could not
find this explicitly documented anywhere, but it is implied by the
definitions in NetBSD's sys/arch/${arch}/include/math.h headers, and the
following assertion from the UBSAN code:
#ifdef __HAVE_LONG_DOUBLE
long double LD;
ASSERT(sizeof(LD) > sizeof(uint64_t));
#endif
RISC-V has 128-bit long doubles, so enable the tests on this platform,
and update the comments to better explain the purpose of this flag.

OpenZFS generates events with a "zio_timestamp" field, which gets mistaken for
"timestamp" by libdevdctl due to imprecise string matching. Then later it is
assumed a "timestamp" field exists when it doesn't and an exception is thrown.
Add a space to the search string so we match exactly "timestamp" rather than
anything with that as a suffix.
