Daniel Lange 088dc5b9a7 Remove license excemption for PLPA and update GPL-2 license text
The Portable Linux Processor Affinity (PLPA) project has been depreciated in
favour of the Portable Hardware Locality (hwloc) project. So the license
exception present in previous versions of htop is obsolete and thus removed.

The text of COPYING has been updated to the latest upstream license text
of GPL-2 from the Free Software Foundation, Inc. (FSF).
There are only editorial changes like line wrapping, removing page breaks,
updating the "19yy" to "<year>" and changing the FSF address.

Christian Göttsche c243db0b2c XUtils: move implementation of String_contains_i out of header file
The function strcasestr(3) is only available if _GNU_SOURCE is defined.
If any file includes <string.h> before declaring _GNU_SOURCE, e.g by
including "config.h", compilation fails with the following error:

Move the implementation to avoid unnecessary includes.
Since LTO is quite common and stable performance should not be impacted
if used.

Christian Göttsche b9e69223d0 ScreenManager: reduce ScreenManager_resize
The main change is the header hight being not included in y1.
This is important if a sub-manager gets resized, e.g. a resize while
editing the Settings or in a pickFromVector selection, and afterwards,
then the sub-manager is closed, the super-ScreenManager gets resized, it
uses the correct header hight.
The header hight might have been changed since the last resize of the
super-manager in the Settings by adding/removing some meters.

This fixes new meters being hidden after added at runtime after a resize
in the main window.

Nathan Scott c7f634ec21 PCP: ensure unsigned types used throughout CPU count detection
This cannot be negative in these code locations, but for the
purposes of static checking like Coverity scan make it clear
and used the same unsigned type as ProcessList.h for the CPU
count variable (matching PL activeCPUs and existingCPUs).

Nathan Scott c401ac3a98 Ensure DynamicColumn hash lookups never see NULL pointers
This cannot happen in these code locations, but for the purposes

add two more guards on NULL hash table entry pointers.

Christian Göttsche 68460b25e3 Reset the signal handlers at program exit
The signal handler will access the Settings struct, which gets freed at
normal program finalization.

When using leak sanitizers with ASAN_OPTIONS=abort_on_error=1, which
runs after program termination, any leak causes SIGABRT to be raised,
calling the crash handler, which will derefernce the freed Settings.

Benny Baumann b42c441ee0 Use proper metric to detect kernel threads
Querying kernel threads with `ps -o pid,lid,flags,state,lname -sp 0`
gives that kernel threads have state `K` and flags have mask `0x20000` set.
This corresponds to `LW_SYSTEM` in kernel which is mapped as `L_SYSTEM`/`P_SYSTEM` for userspace.
