Log:
OLPC Trac 6291 - JFFS2 problem - when there is a gap of more than
0x100 ff bytes (e.g. the tail end of a partially-written page) before
some active nodes in a new page, the raw dirent scanner was giving
up too soon and not seeing the nodes in the following page.  I changed
the scanner to search the entire remainder of the erase block.
