Christian Göttsche 58ad020aca ProcessList: fix treeview on OpenBSD when hiding kernel threads
Currently the tree-view is empty on OpenBSD when kernel threads are
hidden, cause the kernel thread 'swapper' has pid 0 and gets treated as
root of the tree and parent of 'init'.

Do not build any tree with a pid 0 root node.

Christian Göttsche f46fcf094e Linux: Rework libsensors parsing
Do not read driver depended labels, just count the number of
temperatures given:

  on #CPU:
    platform temp = max cpu temp
    CPU temps = first to last
  on #CPU + 1:
    platform temp = first temp
    CPU temps = second to last
  on #CPU / 2:
    platform temp = max cpu temp
    CPU temps = first to last concat first to last
      (with SMT core x + cpu count is the logical core of the physical
      core x)
  on #CPU / 2 + 1:
    platform temp = first temp
    CPU temps = second to last concat second to last
      (with SMT core x + cpu count is the logical core of the physical
      core x)

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 0cfc9b0980 LinuxProcessList: refactor /proc/stat parsing
Combine reading CPU count and CPU usage, only open the file once.
Do not separately initialize totalPeriod and totalTime, cause the value
0 is handled in Platform_setCPUValues().

Take the number of currently running process from the entry
procs_running in /proc/stat instead of counting all scanned process
with state 'R', to include hidden tasks, e.g. threads.

Nathan Scott 5b50ae3aa3 Separate display from sampling in SysArch and Hostname Meters
Several of our newer meters have merged coding concerns in terms
of extracting values and displaying those values.  This commit
rectifies that for the SysArch and Hostname meters, allowing use
of this code with alternative front/back ends.  The SysArch code
is also refined to detect whether the platform has an os-release
file at all and/or the sys/utsname.h header via configure.ac.
