Sparse file support (Completed as of 2.6.22-rc1)

Owner: Mark

Target Release: 1.4

This gains us performance, more efficient usage of space, and has no impact on direct io. It also has the effect of simplifying many critical paths (file write, ftruncate, etc), which will make it easier to implement other allocation changes in the future. This should be done before "Data in inode blocks" and "inline extended attributes" as those two become much easier afterwards.
