Christian Göttsche 550a141860 Add ELAPSED process column
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.

Christian Göttsche 9a8221568a Rework TTY column
* 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.

Christian Göttsche 90ea3ac3c9 Object: return int on comparison
Comparisons do, due to the new introduced shaceship-comparisons,
only return -1, 0, 1 or the result of strcmp().

Christian Göttsche 89473cc9ae Rework enum ProcessField
Use only one enum instead of a global and a platform specific one.
Drop Platform_numberOfFields global variable.
Set known size of Process_fields array

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.

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.

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
    ret

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.
