yaffs: Fix readdir hang.

This aproach uses a search context iterator to allow yaffs to be
unlocked during the filldir. The search context stores the next
object to visited. If changes to the directory (ie unlinks) cause
the directory to be modified then a callback moves the iterator
to the next object if need be, thus preventing the iterator from
being corrupted.
