Bourne shell -> POSIX shell
The FreeBSD shell is a POSIX compatible shell. It evolved over several
decades from the Almquist shell, which was preceeded a decade before
that by the Bourne shell. Most readers today have never seen a Bourne
shell. If someone wants to learn to use our shell, they need to look for
tutorials on the POSIX shell. Align descriptions through out the tree
with this reality, consistent with it's manual and common parlance.
We made a similar change to the doc tree in b4d6eb01540fe.

sound examples: Add mmap example
This example opens separate OSS capture and playback channels in mmap
mode, places them into a sync group, and starts them together so both
ring buffers advance on the same device timeline. It then monitors the
capture mmap pointer with SNDCTL_DSP_GETIPTR, converts that pointer into
monotonic absolute progress using the reported block count, and copies
newly recorded audio from the input ring to the matching region of the
output ring.
The main loop is driven by an absolute monotonic frame clock rather than
a fixed relative usleep delay. Wakeups are scheduled from the sample
rate using a small frame step similar to the SOSSO timing model, while
the audio path itself stays intentionally simple: just copy input to
output, with no explicit xrun recovery or processing beyond ring
wraparound handling.

sys/abi_types.h: time32_t is 64-bit on non-x86 architectures
As long as 'sys/compat/freebsd32/freebsd32.h' is used unconditionally on
all platforms (in 'kern_umtx.c' at least), the rule of thumb is to
ensure that 'struct foo32' on a 32-bit arch is type-compatible with
'struct foo' on the same arch. In practice, this is very simple to
achieve: All 'foo32' types should be compatible with 'foo' on 32-bit
architectures, which is what we are supposed to do already for compat'
structures by design. The recently introduced 'freebsd32_uint64_t' type
typically supports that.
This change fixes commit 87632ddf67b0 ("openzfs sys/types32.h: use
abi_compat.h for time32_t") which was defining 'time32_t' to 'in32_t'
for all 32-bit architectures, which is wrong but on i386. By luck, this
did not change the size of whole 'struct ffclock_estimate32' (whose size
is compile-time asserted) because 'struct bintime32''s one would stay
the same, as even if its field 'sec' was incorrectly sized after that
commit, the 'frac' one is 64-bit and 64-bit aligned on all non-x86
architectures so its offset in 'struct bintime32' would stay the same.

iflib: drain admin task and fix teardown order on register failure
When IFDI_ATTACH_POST() fails (or netmap attach fails), iflib tears down with
ether_ifdetach(), taskqueue_free(ifc_tq), and IFDI_DETACH(). CTX_LOCK is still
held after ether_ifattach. ether_ifdetach() and taskqueue_drain(admin) must not
run under CTX_LOCK.
Teardown ordering (match iflib_device_deregister):
- Free the per-interface admin taskqueue after IFDI_DETACH / IFDI_QUEUES_FREE, not before.
- Drop IFNET_WLOCK() across IFDI_DETACH / IFDI_QUEUES_FREE so driver detach can sleep in
LinuxKPI workqueue drain, then retake IFNET_WLOCK() before iflib_free_intr_mem and fail_unlock.

nfs_diskless: Fix handling of nfsuserd case for NFSv4
Commit 8b9775912cbc added support for an NFSv4 mounted
root file system, but only if the NFSv4 configuration
used id numbers in the strings.
This patch adds support for the case where the NFSv4
configuration uses name<-->id mappings via nfsuserd(8)
by priming the mapping cache with just enough entries
so that it works until the nfsuserd(8) is running.
They are listed in nfs_prime_userd[] in
sys/fs/nfs/nfs_commonsubs.c.
The entries in nfs_prime_userd[] are also wired into
the kernel's cache for name<-->id mappings when nfsuserd(8)
starts up. This is necessary, since an upcall to the
nfsuserd(8) daemon for a mapping when looking up the
path to the passwd/group database files (/etc) will
hang the system, due to a vnode lock being held on
