Some messages of pg_rewind --debug not getting translated

Hi all,

I found that some of the messages generated by pg_rewind --debug are
not getting translated because the string messages are not put within
_(%s). For the debug messages of the file map and the data page map
this is not really a problem because those do not involve any
translatable words like "blk", but for the timeline history file I
think that's a bug. Attached is a patch putting everything under
pg_log(PG_DEBUG) so as we do not rely directly on printf().
Regards,
