This patch adds functionality for generating PUFFDIFF operation, but
since the minor verion has not been increase, it actually does not
generate the operation itself. PUFFDIFF is used for patching deflate
based files.

This patch replaces the Android container related Squashfs images with
their files in the update engine. The location of each new file is
defined as:
'Squashfs image file path' + / + 'the file path inside the Squashfs'
This works even if the files inside the Squashfs are not 4k aligned. But
we need 4k alignment before we add Puffin support. In some experiments
this could even reduce the delta payload size by like 1MB.
