[Qemu-devel] [PATCH V3 0/5] tests: Add the image fuzzer with qcow2 support

[Maria Kustova <maxa@catit.be>]

This patch series introduces the image fuzzer, a tool for stability and
reliability testing.
Its approach is to run large amount of tests in background. During every test a
program (e.g. qemu-img) is called to read or modify an invalid test image.
A test image has valid inner structure defined by its format specification with
some fields having random invalid values.

Patch 1 contains documentation for the image fuzzer, patch 2 is the test runner
and remaining ones relate to the image generator for qcow2 format.

This patch series was created for the 'block-next' branch.

v2 -> v3:
* the runner.py takes binaries under test from environment variables only
* the runner.py accepts JSON with a list of commands under test
* the runner.py has default list of commands under test
* *.ini files for fuzzer configuration were replaced by JSON
* the runner creates backing files of different formats
* the image generator supports backing file name
* the header extensions are generated dependently on available free space
* the specification reflects changes mentioned above
* the specification has the copyright header (based on Eric Blake comments)
