Define a dedicated OnDiskData structure for each on-disk structure. This must match the on-disk layout, except for endianness, which is handled by _SwapEndian methods. These structure are "plain old data" so we can use offsetof on them. They are wrapped in an easier to use C++ API. This resolves a lot of problems with the previous code: warnings caused by the use of offsetof as well as a much simpler instanciation of the objects from on-disk data. Also fixed another problem with UUIDs, where the UUIDs were handled by pointers in a lot of place where it was not necessary. Use references instead. The V4 structures which don't have an UUID will return a "null" (zero-filled) one.
