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 a5db139a0a Linux: use correct column alignment for wide fields
This affects:
- PROC_COMM, PROC_EXE and CWD on Linux
- JAIL on FreeBSD and DragonFlyBSD
- ZONE on Solaris

Christian Göttsche d800d7a3ce Drop usage of formatted error messages from <err.h>
They do not clean up the ncurses environment, leaving the terminal in a
broken state.

Also drop bare usage of exit(3).

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 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.

Nathan Scott f704baeb82 Drop unused global ProcessList memory fields
The global ProcessList structure contains a couple of unused
fields.  'sharedMem' has never been used by any Meter, since
its not been anything other than zero in Linux /proc/meminfo
for many, many years.  The freeMem field is only used in the
usedMem calculation, so it can reside on the stack like some
other memory variables used within-calculations-only and not
exposed to the user via a Meter.

Christian Göttsche 397b5c4bd0 Introduce spaceship comparison for Processes
If currently two unsigned values are compared via `a - b`, in the case b
is actually bigger than a, the result will not be an negative number (as
-1 is expected) but a huge positive number as the subtraction is an
unsigned subtraction.

Avoid over-/underflow affected operations; use comparisons.
Modern compilers will generate sane code, like:
    xor     eax, eax
    cmp     rdi, rsi
    seta    al
    sbb     eax, 0

Zev Weiss a1a027b9bd Axe automated header generation.
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.
