* fix(repository): fixed handling of content.Info Previously content.Info was an interface which was implemented by: * index.InfoStruct * index.indexEntryInfoV1 * index.indexEntryInfoV2 The last 2 implementations were relying on memory-mapped files which in rare cases could be closed while Kopia was still processing them leading to #2599. This changes fixes the bug and strictly separates content.Info (which is now always a struct) from the other two (which were renamed as index.InfoReader and only used inside repo/content/...). In addition to being safer, this _should_ reduce memory allocations. * reduce the size of content.Info with proper alignment. * pr feedback * renamed index.InfoStruct to index.Info
