Zach Brown 3755adddd5 scoutfs: store dirents at multiple hash values ...

Previously we dealt with colliding dirent hash values by storing all the
dirents that share a hash value in a big item with multiple dirents.

This complicated the code and strongly encouraged resizing items as
dirents come and go.  Resizing items isn't very easy with our simple log
segment item creation mechanism.

Instead let's deal with collisions by allowing a dirent to be stored at
multiple hash values.  The code is much simpler.

Lookup has to iterate over all possible hash values.  We can track the
greatest hash iteration stored in the directory inode to limit the
overhead of negative lookups in small directories.
