netpfil: add PF netlink command decoding support
Convert PFNL_CMD values in pf_nl.h from an enum to #define constants,
add a pfnl_cmd table definition for mktable, and implement the
corresponding command decoding helpers in libsysdecode.
This allows mktable to generate PF netlink command lookup tables and
enables symbolic decoding of PF netlink commands.

pfdenied: fix checking root anchor
pfctl doesn't like empty anchors (-a ''), but we can specify the root
anchor as '/' too, so do that instead.

sound: Retire snd_mixer->enuminfo
Instead of caching this when mix_setrecdevs() is called (which many
drivers never call), calculate it when we need it. After all, it is
quite rare that this structure is used by applications.

sound: Remove all remaining uses of mixer_get_lock()
These functions are called from sound(4) through MIXER_SET() in
mixer_set(), but nothing mixer-related is used or needs to be locked in
these cases.

sound: Retire MIXER_SIZE and use correct size in DEFINE_CLASS
I am not sure why this hack was needed, but the size should be
sizeof(struct snd_mixer). Unfortunately, we have to expose snd_mixer,
but it should be better than relying on a hack.

snd_uaudio: Stop using mixer_get_lock()
There is no reason to lock snd_mixer->lock here, since the only thing we
are doing with snd_mixer is to call mix_getdevinfo() and mix_get_dev(),
which are one-line getters, which are needed to eventually call
uaudio_get_child_index_by_dev().

sound: Retire mixer_ioctl_channel()
This function never succeeds when it is not called from the same process
that has opened the file descriptor (e.g., mixer(8)). The reason is that
the CHN_FOREACH() loop tries to match the pid of each channel with the
pid of the process performing the ioctl, which will not be the same,
unless it's the same process that both opened the channel and performed
the ioctl.
In the case that the same process opens the channels and performs the
ioctl, however, we still do not need to worry, because mixer_ioctl_cmd()
essentially does the same thing anyway. Additionally, this scenario
should be quite rare, given that most applications do not open both
/dev/dsp* and /dev/mixer*, and in fact, it is actively encouraged by the
official OSSv4 specification not to do that.

sound: Retire FEEDEQ_DISABLE
We can do this more efficiently by just using the SD_F_EQ* flags. In
fact, the dev.pcm.%d.eq handler will (un)set SD_F_EQ_ENABLED and this is
what we actually test with when choosing to creating the EQ feeder or
not, so setting the state to FEEDEQ_DISABLE does not really an effect in
the first place.

sound: Expose EQ by default
The dev.pcm.%d.eq* sysctls and mixer "bass" and "treble" controls are
exposed only if hint.pcm.%d.eq is set. However, there is no good reason
why we shouldn't at least expose the controls, and let the user
enable/disable/bypass equalization through the sysctl.

(cherry picked from commit a0011c74f8f026e04803b9815198a56f50c247e6)
sound: Retire FEEDEQ_BYPASS
In effect, this is the same as the disable state. There is a comment
that says the bypass state skips EQ altogether, which is what the
disable should be. The disable state according to the comment disables
EQ but keeps the EQ preamp (dev.pcm.%d.eq_preamp), however after testing
it seems that the preamp does not really take effect, because with EQ
disabled, feeder_eq is non existent, so we never execute any EQ code in
the first place.
Make things simpler and clearer and have 2 states; enable and disable,
and do what they should do intuitively.

asmc: add MMIO backend for T2 Macs
T2 Macs (2018+) expose the SMC via memory-mapped registers instead of
I/O ports. Add asmcmmio.c/asmcmmio.h implementing the MMIO transport:
key read/write, getinfo, getbyindex, and a poll-based wait with
exponential backoff.
The driver probes for MMIO at attach time by checking the LDKN firmware
version key; if MMIO is available it is used, otherwise the standard
I/O port backend is used.
T2 fan speeds use IEEE 754 floats instead of fpe2 fixed-point.
Per-fan manual mode uses F%dMd keys instead of the FS! bitmask.
Battery charge limit is exposed via dev.asmc.N.battery_charge_limit.
