nanobsd: embedded: Time stamp the code image
While there is a function nano_makefs() that already takes care of this
issue, we are not yet ready to consume it.
Just add the time stamp and FFS options to makefs. This is done
primarily to use UFS2 (UFS version 2). If the user needs further
customization, the variable NANO_MAKEFS can be overridden. Timestamping
takes care of making the images bit-for-bit identical.

nanobsd: embedded: Fix more regressions from last cleanup
Commit c99bb5747f5e changed "()" grouping into "{}", but in these cases
we chdir and depended on the subshell not changing the directory for the
caller. Restore the old behavior. While things appear to work without
this change, the previous code was intentionally structured this way.

nanobsd: embedded: Remove mtools dependency
Rely on makefs -t msdos to create the MS-DOS partition and remove the

Note that NANO_SLICE_FAT_SIZEs defined in sectors (ending with an "s")
are no longer supported, as a workaround the letter "b" (blocks) may be
used instead.

ndp: Accept multiple queued ND for non-GRAND NAs
Multiple delayed NAs on the same ifa can occur simultaneously.
Therefore:
* Differentiate between GRAND and solicited replies.
* Cancel previous pending GRAND NA for same ifa.
* Reuse ndq memory for GRAND.
* Free non-GRAND replies immediately.
* Don't limit non-GRAND NAs.

llvm: Link cross-tools with static libllvm.a

sound: enforce MASTER volume mute during playback
MASTER mute (vol.mute) works while audio is playing. However, if a
stream is stopped and restarted (PCMTRIG_STOP -> PCMTRIG_START), the
audio will resume even though the mixer shows the MASTER volume as
muted. Other streams that are already playing remain silent. New streams
may also start playing audio regardless of the MASTER mute state.
The volume feeder now considers the MASTER mute when determining whether
a channel should be muted. This ensures MASTER mute is consistently
enforced for all streams and removes the dependency on trigger-driven
state propagation.
Tested with Creative Labs CA0132 card.

Also, add ECN_COMPLETE to support dangerous packet reporting

realpath: Improve prev_len logic
* Save prev_len after having checked for and appended a trailing slash,
not before. This requires us to back up if we end up returning a

* Replace strlcat() with a faster strlcpy() since we know exactly how
far into the buffer we are.

HBSD: Disable retpolines for the bootloader
We've been building the bootloader with retpolines. With the latest
OpenZFS import, the addition of retpolines now causes the loader to be
too large in size, preventing a successful build.
Applying retpolines to the bootloader doesn't make sense, anyways. An
attacker able to exploit speculative execution vulnerabilities at the
bootloader stage has already won the game.
