This will cause ext3 and gfs2 to not compile correctly, but allows us
to get a modern version of ext4 into 3.10. This makes it easier to
backport newer features such as ext4 encryption into a downrev kernel.
It also fixes a number of xfstest failures that were fixed since 3.10.
The subsequent commits will fix up the 3.18 ext4 codebase so it will
compile against 3.10.

Create a new BH_Verified flag to indicate that we've verified all the
data in a buffer_head for correctness. This allows us to bypass
expensive verification steps when they are not necessary without
missing them when they are.
