You need only create a cursor into the representations table, do a
linear walk over the whole table, and that's that. You can see
examples of this in libsvn_fs/bdb/txn-table.c:svn_fs__bdb_get_txn_list().

If I were writing this, I would make this linear walk function live in
bdb/reps-table.c, and it would call a callback function for each row.
That callback would live in libsvn_fs/reps-strings.c, and would use
the functions in that file for reading the representation and string
data, and verifying checksums.
