Christian Göttsche 1e806f9899 RichString: do not unnecessarily clean whole buffer
The local stack buffer does not need to be cleaned to zeros when
  - just initialized, cause the length is set to 0 and the first
    character is set to '\0', so all printing functions will safely stop
  - no further used, i.e. the variable goes out of scope

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.

Christian Göttsche a3cced9fb6 Add option to hide the Function Bar
Support three settings:
  - Always show Function Bar
  - Always hide the Function Bar, except in Infoscreens (Env/Locks...)
    and when editing the search and filter mode
  - Hide the Function Bar on ESC until the next user input

Closes: #439

Christian Göttsche 24c5ca9ddf Panel: rework hight logic
The hight of a Panel dpends on whether the Panel has a header or not.
Also the header migth not be set on Panel creation, like in the
MainPanel. This currently causes the cursor to get hidden behind the
FunctionBar on down-scrolling.

Christian Göttsche e3862aa67e Rework drawing of FunctionBar
Draw the FunctionBar within Panel_draw instead of manually throughout
the code.
Add an optional PanelClass function drawFunctionBar, to allow specific
panels to override the default FunctionBar_draw call.
Rework the code on color change, to really change all colors (selection
markers and panel headers).

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.

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.

Nathan Scott c5808c56db Consolidate repeated macro definitions into one header
The MIN, MAX, CLAMP, MINIMUM, and MAXIMUM macros appear
throughout the codebase with many re-definitions.  Make
a single copy of each in a common header file, and use
the BSD variants of MINIMUM/MAXIMUM due to conflicts in
the system <sys/param.h> headers.

Nathan Scott 8ec5d4a3a0 Further, minor cleanups to headers post-MakeHeaders
Remove leftover empty ifdef/endif pairs, whitespace.
The generated htop.h file was also unused - removed.

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.

It seems that certain negative integer values can crash isalnum().
Let's protect against those.

Explorer09 3d9868833e Fix scrolling behavior change caused by 759caf0f
Commit "Make PgDown behavior more usual." 759caf0f8f
silently changes the PageDown scrolling behavior that, instead of
scrolling one window down until the end of the window touches the end
of the list, the window simply repositions itself in a way that the
selected item always become the last item in the new window.

The commit reverts the behavior, and also fixes sanity conditionals
so that the scrollV variable will _never_ become negative or out-of-
bound.

Fixes issue #532. Also keep the problem #480 addressed.
