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)."

Christian Göttsche d9240999e9 Process: drop commLen
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.

Benny Baumann 77db240b48 Split boilerplate and platform-independent field comparison
This acheives two things:
- Allows for simple tie-breaking if values compare equal (needed to make sorting the tree-view stable)
- Allows for platform-dependent overriding of the sort-order for specific fields

Also fixes a small oversight on DragonFlyBSD when default-sorting.

Hisham Muhammad 3d1703f16f Invert Process_compare resolution so that superclass matches run first
* This removes duplicated code that adjusts the sort direction from every
  OS-specific folder.
* Most fields in a regular htop screen are OS-independent, so trying
  Process_compare first and only falling back to the OS-specific
  compareByKey function if it's an OS-specific field makes sense.
* This will allow us to override the sortKey in a global way without having
  to edit each OS-specific file.

Nathan Scott b7836515e8 Harden the extraction of boot time for the Linux platform
There is a possible path - albeit theoretical really - through
the btime initialization code in Linux ProcessList_new(), when
String_startsWith() is always false, which can result in btime
not being initialized.

This commit refactors the code to remove that possibility.

Nathan Scott a3db2da4a7 Cleanup initialization of jiffies on the Linux platform
Small cleanups - add error handling, remove a local static
variable and refactor LinuxProcess_adjustTime (also rename
it, as its in LinuxProcessList.c not LinuxProcess.c) - and
while there, move the related 'btime' global variable into
LinuxProcessList.c so it can be made static.

Nathan Scott 75e9f9a8d9 Cull the definitions of pageSize and pageSizeKB from CRT.c
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.

Christian Göttsche 157086e750 Split RichString_(append|appendn|write) into wide and ascii
RichString_writeFrom takes a top spot during performance analysis due to the
calls to mbstowcs() and iswprint().

Most of the time we know in advance that we are only going to print regular
ASCII characters.
