Hi all,

This patch aims to provide better test coverage for Allison’s delayed
attribute set. These tests aim to cover cases where attributes are added,
removed, and overwritten in each format (shortform, leaf, node). Error
inject is used to replay these operations from the log.

The following cases are covered in this test:
- empty, add/remove inline attr		(64 bytes)
- empty, add/remove internal attr	(1kB)
- empty, add/remove remote attr		(64kB)
- inline, add/remove inline attr	(64 bytes)
- inline, add/remove internal attr	(1kB)
- inline, add/remove remote attr	(64kB)
- extent, add/remove internal attr	(1kB)
- extent, add multiple internal attr	(inject error on split operation)
- extent, add multiple internal attr	(inject error on transition to node)
- extent, add/remove remote attr	(64kB)
- btree, add/remove multiple internal	(1kB)
- btree, add/remove remote attr         (64kB)
- overwrite shortform attr
- overwrite leaf attr
- overwrite node attr 

Running these tests require the corresponding kernel and xfsprogs changes
that add the new error tags da_leaf_split and attr_leaf_to_node.

v6->v7:
- Rename larp_leaf_to_node to attr_leaf_to_node
- Check that the larp knob is writable
- Cleanup files that were created during testing

Suggestions and feedback are appreciated!

Catherine
