object-store: move lookup_replace_object to replace-object.h

stefanbeller · gitster · commit 47f351e9b328 · 2018-04-12T11:38:56.000+09:00
lookup_replace_object is a low-level function that most users of the
object store do not need to use directly.

Move it to replace-object.h to avoid a dependency loop in an upcoming
change to its inline definition that will make use of repository.h.
