btrfs: pretty print leaked root name I'm a actual human being so am incapable of converting u64 to s64 in my head, so add a helper to get the pretty name of a root objectid and use that helper to spit out the name for any special roots for leaked roots, so I don't have to scratch my head and figure out which root I messed up the refs for.

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.

btrfs: print-tree: pass const extent buffer pointer Since print-tree infrastructure only prints the content of a tree block, we can make them to accept const extent buffer pointer. This removes a forced type convert in extent-tree, where we convert a const extent buffer pointer to regular one, just to avoid compiler warning.

btrfs: print the actual offset in btrfs_root_name We're supposed to print the root_key.offset in btrfs_root_name in the case of a reloc root, not the objectid. Fix this helper to take the key so we have access to the offset when we need it.
