Make UDF use get_bh() instead of directly accessing b_count and use
brelse() instead of udf_release_data() which does just brelse()...

The conversion was generated via scripts, and the result was validated
automatically via a script as well.

It's doing

	if (obh)
		<stuff>
	else
		dereference obh

So presumably `obh' is never null in there.

This defect was found automatically by Coverity Prevent, a static analysis
tool.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
