Ran:
  vi $(git grep --name-only iteritems | grep -v third_party)
  vi $(git grep --name-only itervalues | grep -v third_party)
  vi $(git grep --name-only 'print ' | grep -v third_party)

and edited the files quickly with adhoc macros. Then ran in recipes/:
  ./recipes.py test train

There was only a small subset of files that had been updated to use
six.iteritems() and six.itervalues(). Since the dataset size that is
being used in gclient is small (pretty much always below 200 items),
it's better to just switch to .items() right away and take the temporary
performance hit, so that we don't need to come back to rewrite the code.

This option take the same format as -b / --bug but
spits out "Fixed: #,#" instead of "Bug: #,#".

This CL also looks for fix-, fixed-, and fixes-
branch prefixes and uses those as cue to add "Fixed:"
to the CL description when editing. This is a slight
behavioral change for fix- specifically, as it used
to produce "Bug: " instead.

> In Python 3 byestrings and normal strings can't be concatenated.

In Python 3 byestrings and normal strings can't be concatenated.
To fix this we buffer as bytestrings in the Annotated wrapper.
We can't decode to a string because the output might come byte-by-byte, so it doesn't work with Unicode characters like ✔.

Also had to update gclient_test.py, where double-wrapping stdout with Annotated caused made output not work and include_zero=True working caused other unintended side-effects.

This throws an exception when running with Python 3:

AttributeError: 'str' object has no attribute 'decode'

We are already calling bytes.decode() in enumerate_input(), whose output
is passed to _downloader_worker_thread().
