Changes for version 0.505
- Do required lseek()s in the test-suite since backends no longer do undocumented lseek()s on the target/delta file descriptor
- When trying to load backends, only try loading known backends. The old way was a hacky attempt at loading any possible backend in the Vcdiff namespace.
- Doc updates
- Vcdiff - diff and patch for binary data
- Vcdiff::Test in lib/Vcdiff/Test.pm
