Dive pictures: index local file name by canonical filname

The connection canonical filename to local filename was done via
two maps:
  1) canonical filename -> hash
  2) hash -> local filename
But the local filename was always queried from the canonical filename.
Therefore, directly index the former with the latter.

On startup, convert the old map to the new one.
