haiku/headers/private/storage/mime/Database.h
Tyler Dauwalder 1bd963b6c2 + Added file-extension based mime type guessing
+ Added sniffer rule based mime type guessing
+ Added get_device_icon()
+ Added complete (synchronous, asynchronous; recursive,
  non-recursive; forcing, non-forcing; you name it we got it :-)
  update_mime_info() implementation.
