    fuse: allow caching readdir · 69e34551

    This patch just adds the cache filling functions, which are invoked if
    FOPEN_CACHE_DIR flag is set in the OPENDIR reply.
    
    Cache reading and cache invalidation are added by subsequent patches.
    
    The directory cache uses the page cache.  Directory entries are packed into
    a page in the same format as in the READDIR reply.  A page only contains
    whole entries, the space at the end of the page is cleared.  The page is
    locked while being modified.
    
    Multiple parallel readdirs on the same directory can fill the cache; the
    only constraint is that continuity must be maintained (d_off of last entry
    points to position of current entry).
