• static_vector: added resize with an initializer
• pod_vector: use some algorithms from <alorithm> which improves code generation with MSVC
• atomic: improvements to the interface of atomic_relaxed_counter
• qalgorithm new algorithms:
  • qall_of wraps std::all_of
  • qany_of wraps std::any_of,
  • qnone_of wraps std::none_of
  • New type identity: and identity function similar to std::identity from C++23
