David Sterba 22b46bdc5f btrfs: add forward declarations and headers, part 1
Do a cleanup in the short headers:

- add forward declarations for types referenced by pointers
- add includes when types need them

This fixes potential compilation problems if the headers are reordered
or the missing includes are not provided indirectly.
