object-store.h: move struct object_info from cache.h

Browse Source 
Move struct object_info, and a few related #define's from cache.h to
object-store.h.

A surprising effect of this change is that replace-object.h, which
includes object-store.h, now needs to directly include cache.h since
that is where read_replace_refs is declared and that variable is used
in one of its inline functions.  The next commit will move that
declaration and fix that unfortunate new direct inclusion of cache.h.
