Hisham Muhammad 2327260ee8 Separate tree and list sort orders 
Implements the suggestion from https://github.com/htop-dev/htop/issues/399#issuecomment-747861013

Thanks to the refactors from 0bd5c8fb5da and 6393baa74e5, this was really easy
and clean to do.

It maintains the "Tree view always by PID" option in the Settings, which
results in some specific behaviors such as "clicking on the column header to
exit tree view" and "picking a new sort order to exit tree view", for the sake
of the muscle memory of long time htop users. :)

Zev Weiss 2899ed4cb0 Number CPUs from zero by default. 
Numbering from one is idiosyncratic and inconsistent with basically
everything else in the world; it doesn't make much sense as default
behavior.

All naming is updated to reflect that numbering from one is a
non-default, opt-in option.  The old label of the flag saved in htoprc
("cpu_count_from_zero") is still supported for backwards compatibility
with existing configs, however.

Nathan Scott c9ecd0fa74 Revert the vim_mode setting for now, needs a rethink 
There have been too many bugs reported in vim_mode, and
the proposed fixes are increasingly fragile - hence we
have decided to back it out for now.  For reference:

   https://github.com/htop-dev/htop/issues/69
   https://github.com/htop-dev/htop/pull/37
   https://github.com/htop-dev/htop/pull/106

The whitespace changes also arrived in commit 12805f61d
not sure what that was about, but backed out as well.

Hugo Musso Gualandi 9207401f97 Clean up some code duplication in the header files 
PR htop-dev/htop#70 got rid of the infrastructure for generating header
files, but it left behind some code duplication.

Some of cases are things that belong in the header file and don't need
to be repeated in the C file. Other cases are things that belong in the
C file and don't need to be in the header file.

In this commit I tried to fix all of these that I could find. When given
a choice I preferred keeping things out of the header file, unless they
were being used by someone else.
 2020-09-12 19:20:44 -03:00
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.
