Add a new wrapper to check if a file system supports the newer large
dinode format.  Previously we uses xfs_sb_version_hascrc for that,
which is technically correct but a little confusing to read.

A comment would be useful here to indicate what this means (i.e., we can
assume v3 inode format). The function name is a little vague too I
suppose (will the inode ever get larger than large? :P). I wonder if
something like _has_v3_inode() is more clear, but we can always change
it easily enough and either way is better than hascrc() IMO.

I don't see any logical issues.

I'm not too fond of the v3 name as the check also guards any newer
version (but then again I hope we never need to rev the version..)

/me agrees that this function ought to have a comment saying that
"large_dinode" means v3 inodes.

Not sure about larger than large inodes though -- the last di_flags2
could be made to mean "...and now expand structure by X bytes" whenever
we run out of space.

(The rest of the series looks ok to me)
