[PATCH 2/3] move load_ref_decorations() to log-tree.c and export it

[René Scharfe <rene.scharfe@xxxxxxxxxxxxxx>]

log-tree.c is the ideal place for load_ref_decorations() and its
helper functions to live in, because the variable name_decoration
they're operating on is already located there, so move them thither.
