[PATCH v3 0/9] xfsrestore dirent limitations and scaling issues

[wkendall at sgi.com]

v3 of this series reworks a couple of the patches based on feedback
from Alex Elder:

- 3rd patch: changed a buffer size check to an assert.
- 7th patch: move static functions up in the file and
  create typedefs for segix_t and relnix_t.

The remainder is unchanged from the previous submission.
