From 79008bddf679a5e0900369950eb346c9fa687107 Mon Sep 17 00:00:00 2001

Subject: log: rearrange log function naming
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- 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.
