Jakob Unterwurzacher 84e702126a fusefrontend: implement recursive diriv caching 
The new contrib/maxlen.bash showed that we have exponential
runtime with respect to directory depth.

The new recursive diriv caching is a lot smarter as it caches
intermediate lookups. maxlen.bash now completes in a few seconds.

xfstests results same as
2d158e4c82/screenlog.0 :

  Failed 13 of 580 tests

benchmark.bash results are identical:
