[FL-2675] /int space reservation (#1448)

* 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
