OSError can't be used like a tuple on Python 3, so change the
code to use `e.sterror` instead of `e[1]`.

Instead of manually encoding stderr and stdout output, use
`errors` parameter of subprocess.Popen(). This will make
process.communicate() return unicode strings instead of bytes
objects.

image-fuzzer is now supposed to be ready to run using Python 3.
Remove the __future__ imports and change the interpreter line to
"#!/usr/bin/env python3".

StringIO.StringIO is not available on Python 3, but io.StringIO
is available on both Python 2 and 3. io.StringIO is slightly
different from the Python 2 StringIO module, though, so we need
bytes coming from subprocess.Popen() to be explicitly decoded.

This patch removes support for the cow file format.
Normally we do not break backwards compatibility but in this case there
is no impact and it is the most logical option. Extraordinary claims
require extraordinary evidence so I will show why removing the cow block
driver is the right thing to do.
The cow file format is the disk image format for Usermode Linux, a way
of running a Linux system in userspace. The performance of UML was
never great and it was hacky, but it enjoyed some popularity before
hardware virtualization support became mainstream.
QEMU's block/cow.c is supposed to read this image file format.
Unfortunately the file format was underspecified:
1. Earlier Linux versions used the MAXPATHLEN constant for the backing
filename field. The value of MAXPATHLEN can change, so Linux
switched to a 4096 literal but QEMU has a 1024 literal.
2. Padding was not used on the header struct (both in the Linux kernel
and in QEMU) so the struct layout varied across architectures. In
particular, i386 and x86_64 were different due to int64_t alignment
differences. Linux now uses __attribute__((packed)), QEMU does not.
Therefore:
1. QEMU cow images do not conform to the Linux cow image file format.
2. cow images cannot be shared between different host architectures.
This means QEMU cow images are useless and QEMU has not had bug reports
from users actually hitting these issues.
Let's get rid of this thing, it serves no purpose and no one will be
affected.

If a program under test get frozen, the test should finish and report about its
failure.
In such cases the runner waits for 10 minutes until the program ends its
execution. After this time-out the program will be terminated and the test will
be marked as failed.
For current limitation of test image size to 10 MB as a maximum an execution of
each command takes about several seconds in general, so 10 minutes is enough to
discriminate freeze, but not drastically increase an overall test duration.

The purpose of the test runner is to prepare the test environment (e.g. create
a work directory, a test image, etc), execute a program under test with
parameters, indicate a test failure if the program was killed during the test
execution and collect core dumps, logs and other test artifacts.
The test runner doesn't depend on an image format, so it can be used with any
external image generator.
[Fixed path to qcow2 format module "qcow2" instead of "../qcow2" since
runner.py is no longer in a sub-directory.
