Fixes C-style, redundant, wrong, and dangerous casts (found by Clang-Tidy and cpplint).

• Remove redundant casts. (readability-redundant-casting)
• Remove const_cast. (cppcoreguidelines-pro-type-const-cast)
• Replace C-style casts with static_cast. (google-readability-casting, cpplint: readability/casting)
• Replace unsafe C-style casts with dynamic_cast. (cppcoreguidelines-pro-type-cstyle-cast)
• Replace static_cast in downcasts with dynamic_cast. (cppcoreguidelines-pro-type-static-cast-downcast)
• Replace reinterpret_cast with static_cast or dynamic_cast. (cppcoreguidelines-pro-type-reinterpret-cast)
• Replace two-step casting through void* with reinterpret_cast. (bugprone-casting-through-void)
