rss: make toeplitz.c standard part of the kernel

This will fix LINT-NOIP build. This actually adds very little to the
kernel text, e.g. 500 bytes on amd64. A perfect solution would be to
instead declare rss_config.c as 'optional inet | inet6', but that would
fail to build LINT-NOIP in several NIC drivers, that use RSS and
absolutely ignore that both INET and INET6 are optional. It is very
unlikely that vendors who maintain these drivers will will ever chase the
holy grail of a build that doesn't support IPv4 and IPv6.

xen/acpi: implement hook to notify Xen about entering sleep state

This is required so that ACPI power-off (entering S5) works as expected, as

Additionally, Xen also needs to do cleanup before entering a sleep state,
so it needs to be notified about it.

With this patch FreeBSD dom0 now powers off the host correctly:

Add SPMC (system power management controller) driver as acpi_spmc. This

This supports the original Intel DSM

untested), the AMD DSM (tested), and the Microsoft DSM (tested).

Before entry, acpi_spmc_check_constraints is called to notify of any
violated power constraints. This will use acpi_pwr_get_state to get
current device D-states when that gets added back.

bpf: modularize ifnet(9) part of bpf

Imagine that bpf(9) tapping can happen at any point in the network stack,
not necessarily at interface transmit or receive. To achieve that we need
a thin layer of abstraction defined by struct bif_methods, that defines
how generic bpf layer works with a tap point of this kind.

Implement ifnet(9) specific methods in a separate file bpf_ifnet.c. At
this point there is 100% compatibility for all existing interfaces, there
is no KPI change, yet. The legacy attaching KPI is layered over new ifnet
agnostic KPI. The new KPI may change though, as we can implement multiple
DLTs per single tap point in a prettier fashion.

The new abstraction layer allows us to move all the 802.11 radio injection
hacks out of bpf.c into ieee80211_radiotap.c, so do that immediately as a
good proof of concept.
