log: rearrange log function naming

- Rename log_meta() → log_internal(), to follow naming scheme of most
  other log functions that are usually invoked through macros, but never
  directly.

- Rename log_info_object() to log_object_info(), simply because the
  object should be before any other parameters, to follow OO-style
  programming style.
