These options need to be in the kern.opts.mk file to be alive for kernel

this fix: the host's bsd.opts.mk is irrelevant.

When building out-of-tree modules, it appears that the system share/mk
is used, but sys/conf/kern.mk is used. That results in MK_INIT_ALL_ZERO
being undefined. In the interest of maximum compatability, check
that MK_INIT_ALL_* and COMPILER_FEATURES are defined before comparing
their values.

Otherwise, a socket can have a non-NULL tp->tod while TF_TOE is clear.
In particular, if a newly accepted socket falls back to non-TOE due to
an active open failure, the non-TOE socket will still have tp->tod set
even though TF_TOE is clear.

There are two options:
- WITH_INIT_ALL_ZERO: Zero all variables on the stack.
- WITH_INIT_ALL_PATTERN: Initialize variables with well-defined patterns.
The exact pattern are a compiler implementation detail and vary by type.
They are somewhat documented in the LLVM commit message:
https://reviews.llvm.org/rL349442
I've used WITH_INIT_ALL_* to match Microsoft's InitAll feature rather
than naming them after the LLVM specific compiler flags.
In a range of consumer products, options like these are used in
both debug and production builds with debugs builds using patterns
(intended to provoke crashes on use of uninitialized values) and
production using zeros (deemed more likely to lead to harmless
misbehavior or NULL-pointer dereferences).

uma_zone_reserve()), messages like the following appear on the console:
"Freed UMA keg (Test zone) was not empty (0 items). Lost 528 pages of
memory."
When keg_drain_domain() is draining the zone, it tries to keep the number
of items specified in the reservation. However, when we are destroying the
UMA zone, we do not need to keep those items. Therefore, when destroying a
non-secondary and non-cache zone, we should reset the keg reservation to 0
prior to draining the zone.

Long since then a global tid hash was introduced to remedy
the problem.

In r367327 generic_bs_sr_<n> were derived from mips. Given we are calling

calculations ourselves as eneric_bs_w_<n> will do a str val [bsh, offset].
All we actually have to do is increment offset.

There are workloads with very bursty tid allocation and since unr tries very
hard to have small-sized bitmaps it keeps reallocating memory. Just doing
buildkernel gives almost 150k calls to free coming from unr.
This also gets rid of the hack which tried to postpone TID reuse.

Currently there is no locking done to protect this structure. It is
likely okay due to the low-volume nature of IGMP, but allows for
the possibility of underflow. This appears to be one of the only
holdouts of the conversion to counter(9) which was done for most
protocol stat structures around 2013.
This also updates the visibility of this stats structure so that it can
be consumed from elsewhere in the kernel, consistent with the vast
majority of VNET_PCPUSTAT structures.
