Levi Tamasi 752c87af78 Clean up VersionEdit a bit (#6383 An error occurred ) ... Summary: This is a bunch of small improvements to `VersionEdit`. Namely, the patch * Makes the names and order of variables, methods, and code chunks related to the various information elements more consistent, and adds missing getters for the sake of completeness. * Initializes previously uninitialized stack variables. * Marks all getters const to improve const correctness. * Adds in-class initializers and removes the default ctor that would create an object with uninitialized built-in fields and call `Clear` afterwards. * Adds a new type alias for new files and changes the existing `typedef` for deleted files into a type alias as well. * Makes the helper method `DecodeNewFile4From` private. * Switches from long-winded iterator syntax to range based loops in a couple of places. * Fixes a couple of assignments where an integer 0 was assigned to boolean members. * Fixes a getter which used to return a `const std::string` instead of the intended `const std::string&`.
