AU: Delta Diff Generator
Adds a class that can take two root filesystem image and generate a
delta between them. Currently it's not very well tested, but this will
improve once the diff applicator is written.
Also, an executable to run the generator.
Other changes:
- Stop leaking loop devices in unittests
- extent mapper: support sparse files, ability to get FS block size
- AppendBlockToExtents support sparse files
- subprocess more verbose on errors
- add WriteAll to utils (WriteAll avoids short-write() returns)
- mkstemp wrapper for ease of use
- VectorIndexOf, finds index of an element in a vector
