Kevin Bracey 4a664c0df8 Help: Linux swap consistency
On the help screen's depiction of the swap bar, the / separator between
used and cache should be coloured for consistency with the other bars.

I tried removing the coloured /s from the other bars to make them
consistent, but found that less visually appealing.

Nathan Scott c401ac3a98 Ensure DynamicColumn hash lookups never see NULL pointers
This cannot happen in these code locations, but for the purposes
of static checkers like Coverity scan (and for future proofing),
add two more guards on NULL hash table entry pointers.

Sohaib Mohamed 6f2021f3d9 PCP: support for 'dynamic columns' added at runtime
Implements support for arbitrary Performance Co-Pilot
metrics with per-process instance domains to form new
htop columns.  The column-to-metric mappings are setup
using configuration files which will be documented via
man pages as part of a follow-up commit.

We provide an initial set of column configurations so
as to provide new capabilities to pcp-htop: including
configs for containers, open fd counts, scheduler run
queue time, tcp/udp bytes/calls sent/recv, delay acct,
virtual machine guests, detailed virtual memory, swap.

Note there is a change to the configuration file path
resolution algorithm introduced for 'dynamic meters'.
First, look in any custom PCP_HTOP_DIR location.  Then
iterate, in priority order, users home directory, then
local sysadmins files in /etc/pcp/htop, then readonly
configuration files below /usr/share/pcp/htop.  This
final location becomes the preferred place for our own
shipped meter and column files.

The Settings file (htoprc) writing code is updated to
not using the numeric identifier for dynamic columns.
The same strategy used for dynamic meters is used here
where we write Dynamic(name) so the name can be setup
once more at start.  Regular (static) columns writing
to htoprc - i.e. numerically indexed - is unchanged.

Christian Göttsche 41af31be7f Rework CPU counting
Currently htop does not support offline CPUs and hot-swapping, e.g. via
    echo 0 > /sys/devices/system/cpu/cpu2/online

Split the current single cpuCount variable into activeCPUs and
existingCPUs.

Christian Göttsche fd4e6b432b Use MainPanel type in State struct
The State struct holds a pointer to the main process panel.
Use the distinct MainPanel type, to improve maintainability regrading
its usage.
This avoids usages of down-casts from Panel to MainPanel, only up-casts
from MainPanel to Panel are now required.

David Zarzycki 37e186fd66 Linux: Add SwapCached to the swap meter
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)."

Hisham Muhammad 2327260ee8 Separate tree and list sort orders
Implements the suggestion from https://github.com/htop-dev/htop/issues/399#issuecomment-747861013

Thanks to the refactors from 0bd5c8fb5da and 6393baa74e5, this was really easy
and clean to do.

It maintains the "Tree view always by PID" option in the Settings, which
results in some specific behaviors such as "clicking on the column header to
exit tree view" and "picking a new sort order to exit tree view", for the sake
of the muscle memory of long time htop users. :)

Nathan Scott fee217551c Drop unneeded parameters to the ScreenManager constructor
All calls to ScreenManager_new always pass the same first
five values, the orientation is always HORIZONTAL and the
y1 parameter is always the height of the passed-in header
struct pointer.  I think its safe to assert at this point
that no VERTICAL orientation will arrive (if it does, its
no harm in re-adding this then) - so we can remove unused
conditionals (and TODOs) based on orientation too.
