Christian Göttsche 06b1674aa6 Improve handling when selected last process entry 
If the last process entry is selected and the process dies, stay at the
end of the list and do not jump to the start.

Also if the last entry is selected keep, after rebuilding the process
list due to a new scan, the last entry selected.

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. :)

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.

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.
