image-fuzzer: Return bytes objects on string fuzzing functions
...
No caller of fuzzer functions is interested in unicode string values,
so replace them with bytes sequences.

image-fuzzer: Explicitly use integer division operator
...
Most of the division expressions in image-fuzzer assume integer
division. Use the // operator to keep the same behavior when we
move to Python 3.

image-fuzzer: Fuzzing functions for qcow2 images
...
The fuzz submodule of the qcow2 image generator contains fuzzing functions for
image fields.
Each fuzzing function contains a list of constraints and a call of a helper
function that randomly selects a fuzzed value satisfied to one of constraints.
For now constraints include only known as invalid or potentially dangerous
values. But after investigation of code coverage by fuzz tests they will be
expanded by heuristic values based on inner checks and flows of a program
under test.
Now fuzzing of a header, header extensions and a backing file name is
supported.
