Fix misaligned access inside taskstats structure
...
Reported by UB sanitizer (alongside several other messages):
linux/LinuxProcessList.c:782:25: runtime error: member access within misaligned address 0x614000000264 for type 'struct taskstats', which requires 8 byte alignment
0x614000000264: note: pointer points here
64 01 03 00 0a 00 00 00 00 00 00 00 02 00 00 00 00 00 00 00 4b c8 2e 00 00 00 00 00 3e 45 3c fd
^
The issue doesn't cause trouble on x86, but any architecture with stricter memory alignment requirements may inadvertedly break.

Linux: consider the ZFS ARC to be cache.
...
This commit is based on a patch originally by @edef1c. The ZFS ARC is a cache
(it's in the name), which will be evicted by the kernel if memory pressure so
requires. Hence, the ARC should not be counted towards a system's total used
memory, and should instead be grouped with the other caches in the system.

Axe automated header generation.
...
Reasoning:
- implementation was unsound -- broke down when I added a fairly
basic macro definition expanding to a struct initializer in a *.c
file.
- made it way too easy (e.g. via otherwise totally innocuous git
commands) to end up with timestamps such that it always ran
MakeHeader.py but never used its output, leading to overbuild noise
when running what should be a null 'make'.
- but mostly: it's just an awkward way of dealing with C code.

The Process_sendSignal function is also corrected to have

masked by ignoring this not-quite-harmless warning. I've
also added error checking to the kill(2) call here, which

Refactor openzfs_sysctl_init() and ZfsArcMeter...
...
openzfs_sysctl_init() now returns void instead of int.
The ZfsArcStats->enabled flag is set inside the init function
now, instead of having to be set from its return value.
Preparation for more flag setting in Compressed ARC commit.
ZfsArcMeter_readStats() added and all Meter->values[] setting
moved to it, eliminating duplicated code in
{darwin,freebsd,linux,solaris}/Platform.c.

Move sysfs-reading code to LinuxProcessList.c and add average frequency.
...
This way the frequency is read from sysfs only once per update cycle
instead of every time the UI is redrawn.
This also changes the code to read from /proc/cpuinfo instead. This is because
reading from scaling_cur_freq stalls for 10ms if the previous read for the file
was more than one second ago. [1] Since htop's update cycle is
longer than that, it would cause the read of each CPU's scaling_cur_freq file
to block the UI for 20ms. This easily led to a noticeable half-second lag on
a 20+ CPU machine.
/proc/cpuinfo also has a 10ms delay, but this applies for the whole file
so the delay does not scale with the number of CPUs. [2]

Show N/A instead of 0KHz when CPU frequency is not available.

Add new display option to also show CPU frequency in CPU meters.
...
The option is only implemented on Linux. On other platforms, and on Linuxes
that do not expose the relevant sysfs file, the frequency will be 0.
The "CPU average" meter does not show a frequency, only
the individual per-CPU meters.

Refactor common OpenZFS sysctl access
...
Darwin and FreeBSD export zfs kstats through the
same APIs, so moving functions into a common file.

ZFS arcstats for Linux
...
If no pools are imported (ARC size == 0) or the
ZFS module is not in the kernel (/proc/spl/kstat/zfs/arcstats
does not exist), then the Meter reports "Unavailable".
