While most 64-bit architectures have an assembly implementation of this
file RISC-V does not. As we now copy 8 bytes instead of 4 it should speed
up RISC-V. Using intptr_t instead of int also allows using this file for
CHERI pure-capability code since trying to copy pointers using integer
loads/stores will invalidate pointers.

Apple clang uses a different versioning scheme, so if we enable or

in Apple Clang 11+. This adds 'apple-clang' to COMPILER_FEATURES, so that
bootstrap tools Makefiles can avoid warnings on macOS.

There are a number of issues in the e1000 multicast filter handling
that have been present for a long time. Take the updated approach from
ixgbe(4) which does not have the issues.
The issues are outlined in the PR, in particular this solves crossing
over and under the hardware's filter limit, not programming the
hardware filter when we are above its limit, disabling SBP (show bad
packets) when the tunable is enabled and exiting promiscuous mode, and
an off-by-one error in the em_copy_maddr function.

Only allocate struct_mm after we checked that other threads do not carry
useful mm_struct. If they don't, drop process lock, allocate, and recheck.
Note that for M_NOWAIT allocations we could avoid dropping process lock,
but I do not think that this increased complexity is useful.

Create and use zones for task and mm. Reserve items in zones based on the
estimation of the max number of interrupts in the system. Use M_USE_RESERVE
to allow to take reserved items when allocation occurs from the interrupt
thread context.
Of course, this would only work first time we allocate the task for
interrupt thread. If interrupt is deallocated and allocated anew,
creating a new thread, it might be that zone is depleted. It still
should be good enough for practical uses.

For anonymous objects, provide a handle kvo_me naming the object,
and report the handle of the backing object. This allows userspace
to deconstruct the shadow chain. Right now the handle is the address
of the object in KVA, but this is not guaranteed.
For the same anonymous objects, report the swap space used for actually
swapped out pages, in kvo_swapped field. I do not believe that it is
useful to report full 64bit counter there, so only uint32_t value is
returned, clamped to the max.
For kinfo_vmentry, report anonymous object handle backing the entry,
so that the shadow chain for the specific mapping can be deconstructed.

- Use malloc(9) to allocate ivhd_hdrs list. The previous assumption
that there are at most 10 IVHDs in a system is not true. A counter
example would be a system with 4 IOMMUs, and each IOMMU is related
to IVHDs type 10h, 11h and 40h in the ACPI IVRS table.
- Always scan through the whole ivhd_hdrs list to find IVHDs that has
the same DeviceId but less prioritized IVHD type.

The NAV (network allocation vector) register reflects the current MAC
tracking of NAV - when it will stay quiet before transmitting.
Other devices transmit their frame durations in their 802.11 PHY headers
and all devices that hear a frame - even if it's one in an encoding
they don't understand - will understand the low bitrate PHY header that
includes the frame duration. So, they'll set NAV to this value so
they'll stay quiet until the transmit completes.
Anyway, sometimes the PHY NAV header is garbled and sometimes, notably
older broadcom devices, will fake a long NAV so they can get "cleaner" air
for local calibration. When this happens, the hardware will stay quiet
for quite some time and this can lead to missed/stuck beacons, or
(for Very Large Values) a MAC hang.
This code just adds the ability to get/set the NAV; the driver will
need to take care of using it during transmit hangs and beacon misses
to see if it's due to a trash looking NAV.
