- 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
Allocating zero size memory results in implementation-defined behavior:
man:malloc(3) :
If size is 0, then malloc() returns either NULL, or a unique pointer
value that can later be successfully passed to free().
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.
Improves: #214Closes: #253
man:sysconf(3) states:
The values obtained from these functions are system configuration constants.
They do not change during the lifetime of a process.
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

The issue doesn't cause trouble on x86, but any architecture with stricter memory alignment requirements may inadvertedly break.
- Move swap() macro to source file and implement as function
- Implement Vector_get() and Vector_size() as inline functions
to make them type safe and avoid lhs usage
- Comment comparison statistics, they are only needed for performance
testing
- Remove local types and function from header file
- Reduce OpenFiles_Data to neccessary size
- Print file access mode (r/w/u)
- Fix memory leak on consecutive items without an intermediate file item:
