Update merged command-line when started with "Show custom thread names"
disabled and enabling at runtime.
Also only consider showThreadNames when working on userland threads.
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.
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.

Shared libraries can be replaced by an upgrade, highlight processes
using deleted shared libraries.
Link with highlightDeletedExe setting, enabled by default.
Currently only checked on Linux.
Add process columns showing the elapsed time since the process was
started.
Similar to STARTTIME, but shows the time passed since the process start
instead of the fixed start time of the process.

Make functions formatting data for a process field column less error
prone, unify interfaces and improve some internals.
* Process_printBytes
- rename from Process_humanNumber
- take number in bytes, not kilobytes
- handle petabytes
- increase buffer to avoid crashes when the passed value is
~ ULLONG_MAX
* Process_printKBytes
- add wrapper for Process_printBytes taking kilobytes keeping -1 as
special value
* Process_printCount
- rename from Process_colorNumber
* Process_printTime
- add coloring parameter as other print functions
- improve coloring and formatting for larger times
* Process_printRate
- rename from Process_outputRate
- use local buffer instead of passed one; this function prints to the
RichString after all
`RichString_appendWide()` is more expensive than
`RichString_appendAscii()` due to the calls to `mbstowcs(3)` and
`iswprint(3)`.
Use the latter to print the process field buffer by default.
For the following fields this theoretically can corrupt the output:
- TTY
* Rename internal identifier from TTY_NR to just TTY
* Unify column header on platforms
* Use devname(3) on BSD derivate to show the actual terminal,
simplifies current FreeBSD implementation.
* Use 'unsigned long int' as id type, to fit dev_t on Linux.
Only on Solaris the terminal path is not yet resolved.
Refactor the sample time code to make one call to gettimeofday
(aka the realtime clock in clock_gettime, when available) and
one to the monotonic clock. Stores each in more appropriately
named ProcessList fields for ready access when needed. Every
platform gets the opportunity to provide their own clock code,
and the existing Mac OS X specific code is moved below darwin
instead of in Compat.
A couple of leftover time(2) calls are converted to use these
ProcessList fields as well, instead of yet again sampling the
system clock.

The local stack buffer does not need to be cleaned to zeros when
- just initialized, cause the length is set to 0 and the first
character is set to '\0', so all printing functions will safely stop
- no further used, i.e. the variable goes out of scope
- avoid UBSAN conversions
- print N/A on no data (i.e. as unprivileged user)
- fix rate calculation to show bytes (instead of a thousandth)
- print bytes as human number (i.e. 8MB) instead of 8388608
- stabilize sorting by adjusting NAN values to very tiny negative number
- sort cases by identifier
- use check snprintf
- color nice value of 0 as gray
- color cpu and memory percentages of 0.0 as gray
- color number of threads of 1 as gray
- color idle and sleeping state as gray
- color tgid matching pid (indicating main thread) as gray
If no terminal name can be found, fall back to generic display method
with major and minor device numbers.
Print special value '(none)' in case both are zero.
