- do not reverse CPU steal and guest in monochrome
- black on black in Light Terminal is not visible, use blue on black
- white on blue in Light Terminal is display as blue on black, use
yellow on black
- re-draw FunctionBar after color change
- `CRT_fatalError()` is declared twice in CRT.h
- `Process_pidFormat`, `Process_writeField()` and `Process_compare` are
declared twice in Process.h
- `btime` is defined in LinuxProcess.c and also declared in
LinuxProcess.h, so drop in LinuxProcessList.h
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.
Instead of scanning the meter name to determine the number of columns in a
CPU meter, move the common code behind some wrapper functions, and specify the
number of columns as an explicit parameter when called from the wrappers.
While this does add a bit of code for all the necessary wrapper functions, this
should be less brittle in case of future changes to the CPU meter code.
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.

Use the more portable sysfs node /sys/devices/system/cpu/cpuX/cpufreq/scaling_cur_freq
to get the CPU frequency.
In case of an error fall back to /proc/cpuinfo .
Also use a fixed width of 4 for the frequency to avoid position jumps
in case the frequency moves in the range 900-1100 MHz.
For a process with a very long command, especially with many long
command line arguments, inspecting the command and its arguments could
become inconvenient.
Meanwhile htop supports the concept of "screen", or window, which is
extended here to create a dedicated "CommandScreen", making it possible
to display the command of the selected process in a separate window
meanwhile being wrapped into multiple lines.
Another benefit of using a command screen is, the user can navigate
through the wrapped lines of the command and perform actions like
searching and filtering.
unsigned integer overflows are well-defined, but they might point to a counting issue.
Having the code free of unsigned overflows makes it easier to spot potential bugs.
