4c66eb6d4c XUtils string related updates
- allow count out-parameter of String_split() to be NULL
- introduce xStrndup()
- do not allow NULL pointers passed to String_eq()
  it is not used in any code
- implement String_startsWith(), String_contains_i() and String_eq()
  as inline header functions
- adjust several conversion issues

96e2a4259e Continue to update generic data in paused mode
Generic data, as CPU and memory usage, are used by Meters.
In paused mode they would stop receiving updates and especially Graph
Meters would stop showing continuous data.

Closes: #253

81543253cf Fix misaligned access inside taskstats structure
Reported by UB sanitizer (alongside several other messages):
linux/LinuxProcessList.c:782:25: runtime error: member access within misaligned address 0x614000000264 for type 'struct taskstats', which requires 8 byte alignment
0x614000000264: note: pointer points here
  64 01 03 00 0a 00 00 00  00 00 00 00 02 00 00 00  00 00 00 00 4b c8 2e 00  00 00 00 00 3e 45 3c fd
              ^

The issue doesn't cause trouble on x86, but any architecture with stricter memory alignment requirements may inadvertedly break.

edf1b10d2c Read CPU frequency from sysfs by default
Use the more portable sysfs node /sys/devices/system/cpu/cpuX/cpufreq/scaling_cur_freq
to get the CPU frequency.
In case of an error fall back to /proc/cpuinfo .

Also use a fixed width of 4 for the frequency to avoid position jumps
in case the frequency moves in the range 900-1100 MHz.

00665e2a2b Avoid unsigned integer overflow
unsigned overflow is well defined, but creates noise when using
sanitizers. unsigned overflow can be a symptom of logic issues of
counter, so its reasonable to use.
