Commits on Sep 23, 2024

  1. hashlittle: add a safe variant of hashlittle2 function 

    This variant of hashlittle2() ensures that it avoids
accesses beyond the last byte of the string, which will
cause warnings from tools like Valgrind or Address
Sanitizer.

  2. hyperscan: add caching mechanism for hyperscan contexts 

    Cache Hyperscan serialized databases to disk to prevent compilation
of the same databases when Suricata is run again with the same
ruleset.
The current work operates in /tmp/ folder and caches individual
signature group heads - potentially the ruleset might be even
slightly changed and it still can reuse part of the unchanged
signature groups.
