A process, whose executable has been replaced and thus marked by htop,
can be re-executed with the replaced executable, with the same PID, in
two ways: the Linux feature checkpoint/restore or re-execution of PID 1.
The actual check is just a string comparison, like the dropped
condition, leading to (almost) no computation overhead.
htop has been licensed as GPLv2 but there was inconsistency regarding the
option to choose "any later version" as granted by the license.
This commit clarifies the htop dev team is fine with that choice.
Extending to right neighbors is intended for text meters with an
overlong content, so the whole text is shown if possible.
Multi column meters, like the combined memory and swap meter, position
its text depending on the given total width; keep the position to the
original assigned header slot.
Short term resolution for #796
Select the current active header layout, not the current saved layout
from the settings, as the value gets only saved back from the active
header to settings on closing the setup menu.
Closes: #785
Zero all the CPU data, like totalPeriod, after its memory allocation via
realloc(3).
Conditional jump or move depends on uninitialised value(s)

Use the same width for each sub meter to align with CPU meter.
Currently if the total width is even, so it does not split exactly into
2 equal parts plus 1 (for the middle space character column), the extra
column is added to the second meter width.
