FBT_AFRAMES was skipping over too many frames, while PROFILE_AFRAMES was skipping over too few. Adjust them empirically. (cherry picked from commit 635ecbf47015c259226cb47a3de8fc00c9ed5924)
Experimentation shows this is the correct value; the dtrace/interrupt handler frames are omitted, while the backtrace of the active thread is recorded in its entirety.

With clang 15, the following -Werror warnings is produced:
sys/cddl/dev/profile/profile.c:640:15: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
profile_unload()
^
void
This is because profile_unload() is declared with a (void) argument
list, but defined with an empty argument list. Make the definition match
the declaration.

In both cases, too few frames were trimmed, leading to exception handling or DTrace internals being exposed in stack traces exposed by D's stack() primitive.

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. Sponsored by: iXsystems, Inc. Differential Revision: https://reviews.freebsd.org/D25872
r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE. All entries that haven't been marked as MPSAFE before are by default marked as NEEDGIANT Approved by: kib (mentor, blanket) Commented by: kib, gallatin, melifaro Differential Revision: https://reviews.freebsd.org/D23718
Even though there do appear to be more artificial frames, with 12, stack traces no longer list at all. Revert until a better, more stable value can be determined.
