9b31ee5b63 Drop taskstats conditional 
taskstats is only checked on runtime if the column RCHAR, WCHAR, SYSCR,
SYSCW, RBYTES, WBYTES, CNCLWB, IO_READ_RATE, IO_WRITE_RATE or IO_RATE is
selected.

taskstats is currently enabled by default.

Drop the taskstats configuration switch, to reduce the maintenance cost.

cgroup is only checked on runtime if the column CGROUP is selected.

cgroup is currently disabled by default, but most distributions do
enable it.

c75c5ef9c6 Minor cleanups to platform-specific init and done 
Move platform-specific code out of the htop.c main function
and into the platform sub-directories - primarily this is
the Linux procfs path check and sensors setup/teardown; not
needed on any other platforms.  No functional changes here.

397b5c4bd0 Introduce spaceship comparison for Processes 
If currently two unsigned values are compared via `a - b`, in the case b
is actually bigger than a, the result will not be an negative number (as
-1 is expected) but a huge positive number as the subtraction is an
unsigned subtraction.

Avoid over-/underflow affected operations; use comparisons.
Modern compilers will generate sane code, like:
    xor     eax, eax
    cmp     rdi, rsi
    seta    al
    sbb     eax, 0
    ret

9ee72568dc CPUMeter: add octuple-column CPU meters. 
This is a straightforward extension of the existing multi-column CPU meter
code, which now allows for up CPU meters to be displayed in up to 16 columns.

This also adds the meter declarations to all the platform-specific code.

dfa40ad0eb 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.

a1a027b9bd 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.

81b64691a7 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]

08feb8585b Add pressure stall information (PSI) meters on Linux 
The pressure stall information (PSI) metrics provide useful information
on delays caused by waiting for CPU, IO and memory. Particularly on busy
servers it can provide a quick overview of what's "slowing things down".

This feature is supported on Linux >= 4.20.
The interface is documented here:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/plain/Documentation/accounting/psi.txt
These links provide rationale:
https://lwn.net/Articles/759781/
https://facebookmicrosites.github.io/psi/

The following metrics are added, corresponding to the currently exposed
lines (see `head /proc/pressure/*`):
- PressureStallCPUSome
- PressureStallIOSome
- PressureStallIOFull
- PressureStallMemorySome
- PressureStallMemoryFull

The color scheme is the same as that used for Load Average, however I
gave it separate entries just in case someone wants to change them
specifically.

Tested on 4.20.7-arch1-1-ARCH, on the linux platform.
Also tested that other platforms still compile (changed configure to use
the unsupported platform).

Closes #879.

da60309fc9 Don't follow process when selecting non-process-specific options 
Disable the follow process logic in Action_pickFromVector(), when
selecting sort order or user filter, since they don't apply on specific
process.

Fix #856

Remove unnecessary HAVE_SYS_SYSMACROS_H check 
HAVE_SYS_SYSMACROS_H is always true if MAJOR_IN_SYSMACROS.

This way of checking is recommended in autoconf 2.70 documentation:
https://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=blobdiff;f=doc/autoconf.texi;h=4f041bd4e;hp=9ad7dc1c5f02c8ba25b2fe1218bf931c7113a5d5;hb=e17a30e987d7ee695fb4294a82d987ec3dc9b974;hpb=565a6dc50cfa01cec2fb4db894026689cdf4970c

NOTE: currently
      https://www.gnu.org/software/autoconf/manual/autoconf.html is the
      doc for autoconf 2.69.

bd1d719a61 Linux: add process->starttime and use it for STARTTIME column (#700) 
this way a remount of /proc will not reset starttimes
and we can also see startup times for processes started before the mount
of /proc

also record btime (boot time in seconds since epoch) as Linux semi-global
