Update to 1.80b:

--------------
Version 1.80b:
--------------

  - Made afl-cmin tolerant of whitespaces in filenames. Suggested by
    Jonathan Neuschafer and Ketil Froyn.

  - Added support for AFL_EXIT_WHEN_DONE, as suggested by Michael Rash.

--------------
Version 1.79b:
--------------

  - Added support for dictionary levels, see testcases/README.testcases.

  - Reworked the SQL dictionary to use levels.

  - Added a note about Preeny.

--------------
Version 1.78b:
--------------

  - Added a dictionary for PDF, contributed by Ben Nagy.

  - Added several references to afl-cov, a new tool by Michael Rash.

  - Fixed a problem with crash reporter detection on MacOS X, as reported by
    Louis Dassy.

--------------
Version 1.77b:
--------------

  - Extended the -x option to support single-file dictionaries.

  - Replaced factory-packaged dictionaries with file-based variants.

  - Removed newlines from HTML keywords in testcases/_extras/html/.

--------------
Version 1.76b:
--------------

  - Very significantly reduced the number of duplicate execs during
    deterministic checks, chiefly in int16 and int32 stages. Confirmed
    identical path yields. This should improve early-stage efficiency by
    around 5-10%.

  - Reduced the likelihood of duplicate non-deterministic execs by
    bumping up lowest stacking factor from 1 to 2. Quickly confirmed
    that this doesn't seem to have significant impact on coverage with
    libpng.

  - Added a note about integrating afl-fuzz with third-party tools.
