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.

(SHT_PROGBITS instead of SHT_NOTE). Previously, sed was used on the

in assembly which permits setting the correct section type directly.
While here, move inline assembly entry points out of C and into assembly

libc cannot assume that aligned_alloc and free come from jemalloc, or that
any application providing its own malloc and free is actually providing
aligned_alloc.
Switch back to malloc and just make sure we're passing a properly aligned
stack into rfork_thread, as an application perhaps can't reasonably replace
just malloc or just free without headaches.
This unbreaks ksh93 after r361996, which provides malloc/free but no
aligned_alloc.

Some environments in which execvPe may be called have a limited amount of
stack available. Currently, it avoidably allocates a segment on the stack
large enough to hold PATH so that it may be mutated and use strsep() for
easy parsing. This logic is now rewritten to just operate on the immutable
string passed in and do the necessary math to extract individual paths,
since it will be copying out those segments to another buffer anyways and
piecing them together with the name for a full path.
Additional size is also needed for the stack in posix_spawnp(), because it
may need to push all of argv to the stack and rebuild the command with sh in
front of it. We'll make sure it's properly aligned for the new thread, but
future work should likely make rfork_thread a little easier to use by
ensuring proper alignment.
Some trivial cleanup has been done with a couple of error writes, moving
strings into char arrays for use with the less fragile sizeof().

If execve fails with ENOEXEC, execvp is expected to rebuild the command
with /bin/sh instead and try again.
The previous version did this, but overlooked two details:
argv[0] can conceivably be NULL, in which case memp would never get
terminated. We must allocate no less than three * sizeof(char *) so we can
properly terminate at all times. For the non-NULL argv standard case, we
count all the non-NULL elements and actually skip the first argument, so we
end up capturing the NULL terminator in our bcopy().
The second detail is that the spec is actually worded such that we should
have been preserving argv[0] as passed to execvp:
"[...] executed command shall be as if the process invoked the sh utility
using execl() as follows:
execl(<shell path>, arg0, file, arg1, ..., (char *)0);
where <shell path> is an unspecified pathname for the sh utility, file is
the process image file, and for execvp(), where arg0, arg1, and so on
correspond to the values passed to execvp() in argv[0], argv[1], and so on."
So we make this change at this time as well, while we're already touching
it. We decidedly can't preserve a NULL argv[0] as this would be incredibly,
incredibly fragile, so we retain our legacy behavior of using "sh" for
argv[] in this specific instance.
Some light tests are added to try and detect some components of handling the
ENOEXEC fallback; posix_spawnp_enoexec_fallback_null_argv0 is likely not
100% reliable, but it at least won't raise false-alarms and it did result in
useful failures with pre-change libc on my machine.
This is a secondary change in D25038.
