btrfs: tree-checker: Add EXTENT_ITEM and METADATA_ITEM check
This patch introduces the ability to check extent items.
This check involves:
- key->objectid check
Basic alignment check.
- key->type check
Against btrfs_extent_item::type and SKINNY_METADATA feature.
- key->offset alignment check for EXTENT_ITEM
- key->offset check for METADATA_ITEM
- item size check
Both against minimal size and stepping check.
- btrfs_extent_item check
Checks its flags and generation.
- btrfs_extent_inline_ref checks
Against 4 types inline ref.
Checks bytenr alignment and tree level.
- btrfs_extent_item::refs check
Check against total refs found in inline refs.
This check would be the most complex single item check due to its nature
of inlined items.
