For now, the semantics are mostly fit for Linux zswap subsystem. For
instance, we add the third swap usage metric that indicates the amount
of memory that is accounted to swap but in fact stored elsewhere. This
exactly matches the definition of frontswap/zswap, and is probably of
little use to all other platforms.

Show both compressed and uncompressed bars.

Highlight processes started from binaries with file capabilities set,
like kwin_wayland, or retaining Linux capabilities, via the ambient set,
after switching from the root user, e.g. rtkit.

On NetBSD state 'R' means runnable not running.
Improve the color identifier name accordingly.

The signal handler will access the Settings struct, which gets freed at
normal program finalization.
When using leak sanitizers with ASAN_OPTIONS=abort_on_error=1, which
runs after program termination, any leak causes SIGABRT to be raised,
calling the crash handler, which will derefernce the freed Settings.

SUMMARY: AddressSanitizer: heap-use-after-free /home/christian/Coding/workspaces/htop/Settings.c:329:26 in Settings_write

This commit is based on exploratory work by Sohaib Mohamed.
The end goal is two-fold - to support addition of Meters we
build via configuration files for both the PCP platform and
for scripts ( https://github.com/htop-dev/htop/issues/526 )
Here, we focus on generic code and the PCP support. A new
class DynamicMeter is introduced - it uses the special case
'param' field handling that previously was used only by the
CPUMeter, such that every runtime-configured Meter is given
a unique identifier. Unlike with the CPUMeter this is used
internally only. When reading/writing to htoprc instead of
CPU(N) - where N is an integer param (CPU number) - we use
the string name for each meter. For example, if we have a
configuration for a DynamicMeter for some Redis metrics, we
might read and write "Dynamic(redis)". This identifier is
subsequently matched (back) up to the configuration file so
we're able to re-create arbitrary user configurations.
The PCP platform configuration file format is fairly simple.
We expand configs from several directories, including the
users homedir alongside htoprc (below htop/meters/) and also
/etc/pcp/htop/meters. The format will be described via a
new pcp-htop(5) man page, but its basically ini-style and
each Meter has one or more metric expressions associated, as
well as specifications for labels, color and so on via a dot
separated notation for individual metrics within the Meter.
A few initial sample configuration files are provided below
./pcp/meters that give the general idea. The PCP "derived"
metric specification - see pmRegisterDerived(3) - is used
as the syntax for specifying metrics in PCP DynamicMeters.

Add command line option to disable all system and process changing
features.
|
|
Always show the number of kernel and userland threads, even when they
are disabled to not be shown in the process list.
The data is already available and might improve understanding the system
utilization.
Use a shadow color in case the kind of thread is hidden, else the normal
meter one.

Shmem: Total memory used by shared memory (shmem) and tmpfs

Closes: #556

This removes the call-sites of the removed setuid feature
|
|
This support was rarely ever used and has been disabled by default for some time.
As far as the developer team is aware there's no distribution that activated this
feature in their packages by default.

According to the Linux kernel documentation, "SwapCached" tracks "memory
that once was swapped out, is swapped back in but still also is
in the swapfile (if memory is needed it doesn't need to be swapped out
AGAIN because it is already in the swapfile. This saves I/O)."

By storing the per-process m_resident and m_virt values in the form
htop wants to display them in (KB, not pages), we no longer need to
have definitions of pageSize and pageSizeKB in the common CRT code.
These variables were never really CRT (i.e. display) related in the
first place. It turns out the darwin platform code doesn't need to
use these at all (the process values are extracted from the kernel
in bytes not pages) and the other platforms can each use their own
local pagesize variables, in more appropriate locations.
Some platforms were actually already doing this, so this change is
removing duplication of logic and variables there.

Show the CPU temperature in the CPU meter, like CPU frequency, instead
of using an extra Meter.

man:sysconf(3) states:
The values obtained from these functions are system configuration constants.
They do not change during the lifetime of a process.

This should be done as all platforms essentially did the same anyway and there was nothing platform specific.

Add a date meter and sort header and source files in Makefile
Change the lists of header and source files sorted alphabetical and one
file per line. This way diffs become better readable and merges easier.
