* storage: added global #defines for /int, /ext & /any * storage: introduced PATH_EXT, PATH_INT& PATH_ANY macros * core apps: moved hardcoded config files names to separate headers; prefixed them with "."; updater: added file name migration to new naming convention on backup extraction * storage: fixed storage_merge_recursive handling of complex directory structures; storage_move_to_sd: changed data migration logic to all non-dot files & all folders * core: added macro aliases for core record names * Bumped protobuf commit pointer * storage: reserved 5 pages in /int; denying write&creation of non-dot files when running out of free space Co-authored-by: あく <alleteam@gmail.com>
