Version ++4.31c (release)

• SAND mode added (docs/SAND.md) for more effecient fuzzing with sanitizers
  (thanks to @wtdcode !)
• afl-fuzz:
  • splicing phase is now DISABLED by default because research showed
    it is counterproductive. New command line parameter -u to enable
    it. Splicing is auto-enabled if two cycles without finds happen.
  • Python 3.13+ support
  • loose file and shared memory permissions on Android and iPhone
• afl-cc:
  • LLVM 20 support (again - please don't change the API all the time ...)
  • -fsanitize=fuzzer now inserts libAFLDriver.a addtionally early to help
    compiling if LLVMFuzzerTestOneOnput is in an .a archive
  • added _sanitizer_weak_hook* functions (in case that is helpful in
    weird setups)
  • fix bug with large map sizes when multiple libraries are loaded after
    the shared memory was obtained.
