fs: btrfs: Crossport structure accessor into ctree.h

This brings all structure accessors from btrfs-progs/ctree.h, as in
kernel's ctree.h.

All these accessors handle the endian convert at runtime, and since all
of them are defined as static inline functions, those which aren't used
won't take space in resulting binary.
