[XFS] add generic btree types

Add generic union types for btree pointers, keys and records. The generic
btree pointer contains either a 32 and 64bit big endian scalar for short
and long form btrees, and the key and record contain the relevant type for
each possible btree.

Split out from a bigger patch from Dave Chinner and simplified a little
further.
