Add IOMAP_REPORT support to ext4, including support for inline data
which iomap couldn't report so far.  Switch to iomap_seek_{hole,data} on
ext4.

This patch set seems to be working correctly on ext4 as well as xfs
under xfstests.  Jan Kara has pointed out an issue that I can't
reproduce though, so please review carefully.

Thanks,
Andreas
