btrfs: add raid stripe tree definitions
Add definitions for the raid stripe tree. This tree will hold information
about the on-disk layout of the stripes in a RAID set.
Each stripe extent has a 1:1 relationship with an on-disk extent item and
is doing the logical to per-drive physical address translation for the
extent item in question.
