xfs: convert rt bitmap extent lengths to xfs_rtbxlen_t
XFS uses xfs_rtblock_t for many different uses, which makes it much more difficult to perform a unit analysis on the codebase. One of these (ab)uses is when we need to store the length of a free space extent as stored in the realtime bitmap. Because there can be up to 2^64 realtime extents in a filesystem, we need a new type that is larger than xfs_rtxlen_t for callers that are querying the bitmap directly. This means scrub and growfs. Create this type as "xfs_rtbxlen_t" and use it to store 64-bit rtx lengths. 'b' stands for 'bitmap' or 'big'; reader's choice. Signed-off-by: Darrick J. Wong <djwong@kernel.org>
