Daniel Lange a0fb6e34f9 Merge branch 'number-cpus-from-zero' of zevweiss/htop
* This changes the default to count CPUs from zero (instead of starting at one)
* Settings logic is inverted, backwards compatibility is preserved

Christian Göttsche 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

Christian Göttsche 577416d1a9 Assert allocating non-zero size memory
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().

Christian Göttsche 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

Christian Göttsche 361877454f Cache PAGE_SIZE
man:sysconf(3) states:
    The values obtained from these functions are system configuration constants.
    They do not change during the lifetime of a process.

resuming process tracing:

Benny Baumann 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.
