This syncs accessors.[ch] from the kernel. For the most part
accessors.h will remain the same, there's just some helpers that need to
be adjusted for eb->data instead of eb->pages. Additionally accessors.c
needed to be completely updated to deal with this as well.
This is a set of files where we will likely only sync the header going
forward, and leave the C file in place as it needs to be specific to
btrfs-progs.
This forced a few "unrelated" changes
- Using btrfs_dir_item_ftype() instead of btrfs_dir_item_type(). This
is due to the encryption changes, and was simpler to just do in this
patch.
- Adjusting some of the print tree code to use the actual helpers and
not the btrfs-progs ones.
A local definition of static_assert is used to avoid compilation
failures on older gcc (< 9) where the 2nd parameter is mandatory.
