It is only used on Linux to optimize memory handling in case the command
changes to a smaller-or-equal string.
This "optimization" however causes more code bloat and maintenance cost
on string handling issues than it gains.
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.
Generic data, as CPU and memory usage, are used by Meters.
In paused mode they would stop receiving updates and especially Graph
Meters would stop showing continuous data.

man:sysconf(3) states:
The values obtained from these functions are system configuration constants.
They do not change during the lifetime of a process.
Reasoning:
- implementation was unsound -- broke down when I added a fairly
basic macro definition expanding to a struct initializer in a *.c
file.
- made it way too easy (e.g. via otherwise totally innocuous git
commands) to end up with timestamps such that it always ran
MakeHeader.py but never used its output, leading to overbuild noise
when running what should be a null 'make'.
- but mostly: it's just an awkward way of dealing with C code.
Squashed the following commits:
* Solaris: Get LWP enumeration working
* Solaris: Make showing and hiding of kernel threads behave
* Solaris: remove usage of lwpstatus that is no longer needed
* Solaris: no discrete access to parent proc structure needed
* Solaris: Restore runtime MaxPid detection after LWP changes
* Solaris: Workaround virtual PID signal issue by shadowing kill() with a macro
* Solaris: Fix unintention double-shifting of virtual PID for LWP enumeration
* Solaris: Add LWPID to default display since LWP enumeration is also default
* Solaris: use PAGE_SIZE_KB from Process.h instead of custom definition
* Solaris: stop LWP enumeration at 1023 LWPs per proc since that is all we can handle in the virtual PID
This commit adds support for Solaris, squashed from PR #741:
Summary of additions:
* Initial setup of Solaris platform directory
* Add Solaris platform into autoconf template
* Uptime and load averages
* Add dependency on libkstat
* Basic process listing
* Zone name display
* CPU detection
* Per-process memory and CPU usage parsed correctly
* Uses sysconf to discover number of CPUs, instead of more complex libkstat code
* Simple memory display working
* Reduce repetitive calls to the PAGE_SIZE macro when reading memory info
* Add Project, Contract, Task, and Pool into process properties
* Use system major()/minor() implementations and remove extraneous definition of mkdev()
* Get the STARTTIME column working properly, using the Linux implementation as a guide
