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.

nia 2ab8fb83ba netbsd: Support curses libraries without ncurses mouse support
This adds a configure check for the ncurses getmouse() function
and disables mouse-related code paths when mouse support is
not present in the curses library.

This is necessary for stable versions of NetBSD's libcurses, the
development version has stub mouse functions for compatibility
with ncurses.

Scott Olson d45b4f4a43 Use PATH lookup for systemctl in systemd meter
Before this change, the systemd meter was broken on distros like NixOS,
which have systemctl in PATH, but not at /bin/systemctl. After the
change, it works on all my NixOS machines.

Nathan Scott bf853addc3 Ensure PCP dynamic metric configuration definition uniqueness
It can happen that pcp-htop is presented multiple definitions
of the same dynamic meter, e.g. if /etc/pcp/htop/meters has a
definition matching one in ~/.config/htop/meters - instead of
exiting with a duplicate metric error provide more meaningful
diagnostics (on close) and also just skip over such entries.
System files override home directories which overrides those
found below the current working directory.

Also fix the derived metric error diagnostic; because this is
using CRT_fatalError, which is like perror(3), we must give a
meaningful prefix (like program name) at the string end.

This SIGINT handler is installed on top of an optional
handler that some curses/ncurses implementations provide.

Nathan Scott 01f5b89278 Pretty-print values in the PCP DynamicMeter code
Several improvements to the way values are displayed in the
PCP platform DynamicMeter implementation:
- handle the initial 'caption' setting as with regular meters,
  this required a new meter callback because we no longer have
  just a single meter caption for the DynamicMeter case
- if no label is provided for a metric in a configuration file
  use the short form metric name as a fallback
- honour the suffix setting in the configuration file
- convert metric values to the canonical units for htop (kbyte
  and seconds), and use Meter_humanUnit when it makes sense to
  do so.

Also improves the handling of fatal string error messages in a
couple of places, thanks to BenBE for the review feedback.

Nathan Scott f0ed0fdafb Add a new DynamicMeter class for runtime Meter extension
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.

Nathan Scott a0f758009b Fix bitmask used to extract CPU identifier for CPUMeter
When manipulating CPUMeters in the AvailableMeterPanel we
use the bottom 16 bits to hold the CPU number.  However,
the bitmask used to extract the CPU number only masks the
lower 8 bits (0xff).
