* Bug fixes:
  - When passing files on the command line, don't call specialize(..) before
    we've checked that the files are identical. In the worst case, this was
    resulting in spinning up binwalk and extracting two entire filesystem
    images merely to confirm that they were indeed filesystem images..
    before simply concluding that they were identical anyway.
  - Do not exit with a traceback if paths are inaccessible, either directly,
    via symbolic links or within a directory. (Closes: #1065498)
  - Correctly identify changes to only the line-endings of files; don't mark
    them as "Ordering differences only".
  - Use the "surrogateescape" mechanism of str.{decode,encode} to avoid a
    UnicodeDecodeError and crash when decoding zipinfo output that is not
    valid UTF-8. (Closes: #1093484)
* Testsuite changes:
  - Don't mangle newlines when opening test fixtures; we want them untouched.
  - Move to assert_diff in test_text.py.
* Misc:
  - Remove unnecessary return value from check_for_ordering_differences in
    the Difference class.
  - Drop an unused function in iso9600.py
  - Inline a call/check of Config().force_details; no need for an additional
    variable.
