ahc(4)/ahd(4): target mode: cancel outstanding AIOs and INOTs
When disabling a lun there can still be outstanding AIOs and INOTs, when
this happens previously the lun would just fail to disable and trying to
re-use the lun would break the card.
isp(4) in target mode does the same thing when disabling a lun, in
testing this allows re-starting of ctld(8) with connected initiators and
allows initiators to gracefully resume afterwards.

pow,powf(3),__ieee754_rem_pio2(f): Avoid negative integer left shift UB
A compiler clever enough to know that z is positive with a non-zero
biased exponent could, for example, optimize away the scalbnf(z,n) in
pow() because behavior for left shift of negative values is undefined.
`n` is negative when y*log2(|x|) < -0.5. i.e. |x^y| < sqrt(0.5)
The intended behavior for operator<< in this code is to shift the two's
complement representation of the first operand.
In the pow() functions, the result is added to the IEEE 754 exponent of
z = 2^y'. n may be negative enough to underflow the biased IEEE 754
exponent below zero, which is manifested in the sign bit of j
(which would correspond to the IEEE 754 sign bit).
The conversion from uint32_t to int32_t for out-of-int32_t-range values
is implementation defined. The assumed behavior of interpreting the
uint32_t value as a two's complement representation of a signed value
is already assumed in many parts of the code, such as uses of

__vprintf(): switch from strerror() to strerror_rl()
This eliminates the use of non-thread-safe function in printf*() family,
and make the call locale-aware. Also, it stops obliterating the
strerror() static buffer, which aligns with the POSIX requirement that
implementations must behave as if no standard-mandated functions call
strerror().

nfsserver: Default to nfs_reserved_port_only="YES"
This setting causes the NFS server to check that all RPCs are sent from
a privileged (<= 1023) port, rejecting those that are not. This
slightly raises the bar for a user with network access to an
unauthenticated NFS server to access exported NFS filesystems.
Users that use traditional NFS clients (e.g., those provided by FreeBSD
or Linux) should not see any difference, assuming that unprivileged
filesystem mounting is disallowed.
Note that the setting is per-VNET, so may be overridden in VNET jails
without affecting the rest of the system.

L2ARC: Cleanup buffer re-compression
When compressed ARC is disabled, we may have to re-compress when
writing into L2ARC. If doing so we can't fit it into the original
physical size, we should just fail immediately, since even if it
may still fit into allocation size, its checksum will never match.
While there, refactor the code similar to other compression places
without using abd_return_buf_copy().
