* fix: Use default rcl allocator if allocator is std::allocator This fixes a bunch of warnings if using ASAN / valgrind on newer OS versions. It also fixed a real bug, as giving the wrong size on deallocate is undefined behavior according to the C++ standard. This version of the patch keeps the behavior for users that specified an own allocator the same and in therefore back portable. Signed-off-by: Janosch Machowinski <J.Machowinski@cellumation.com> * feat: Provide a way to suppress the deprecation warning This commit adds the feature, that the user can now specify a method rcl_allocator_t get_rcl_allocator() on the given allocator. This method will be called if present, to get the rcl allocator. If the method is not present, the code will fall back to the old (and faulty) implementation and show a deprecation warning.
