Add a basic backwards compatibility unittest.

This verifies we can still apply old patches, but does not
verify that old clients can apply new patches. That seems
important, but I'm not sure how to do it without storing
old client binaries in version control.

Also refactors a number of unit tests to allow code sharing for
reading files into memory. This is done via a new base class.

Uses test binaries submitted seperatly because of build tools problems.

BUG=None
TEST=New Unittest
