Hello,

recently, syzbot evidently found an efficient way to fuzz UDF filesystem images
creating subtly corrupted directories which were causing all sorts of trouble
for UDF directory handling code. The code has already been rather convoluted
so it was not really easy to plug the holes syzbot found. The patch set
rewrites udf directory handling code to a more managable codebase and as an
side-effect also fixes several syzbot reports.

I plan to queue the patches to my tree.
