From: "Darrick J. Wong" <darrick.wong@xxxxxxxxxx>
A few tweaks to the extended attribute editing APIs:
* Use size_t, not unsigned int, in the new extended attribute editing
API.
* Don't expose the _expand() call since there should be no external
users.
* Add a function to return the number of attributes.
