* Stratosphere: Use modern C++ idioms in some places * algorithms like std::for_each are used instead of raw loops * Stratosphere: Replace more raw loops with algorithms * Stratosphere: Add a utility predicate function to test for equality with a reference element This can be used to rewrite some common raw loops using algorithms instead * fs.mitm: Use variant * fs.mitm: Use enum class * fs.mitm: Turn RomFSSourceInfo::Cleanup into a destructor This obsoletes the need for a custom deleter in other places * fs.mitm: Use enum class some more * fs.mitm: Use unique_ptr * fs.mitm: Simplify initialization * Stratosphere: Simplify initialization * fs.mitm: Use unique_ptr (fix memory leak along the way) The previous code was using "delete" rather than "delete[]" * fs.mitm: Use vector::emplace_back rather than push_back emplace_back constructs elements in-place, hence avoiding a redundant element copy. * Stratosphere: Replace more raw loops with algorithms * Stratosphere: Use unique_ptr * fs.mitm: Replace more raw loops with algorithms * Stratosphere: Prefer move-construction over copy-construction when moving sink parameters around
