All these are calling subprocess in 'text mode', where it will
try to decode stdout/stderr using the default encoding (utf-8
for us). If it doesn't decode, subprocess will raise an exception
and kobo doesn't handle it, it just passes it along to us, so
things blow up - see https://pagure.io/releng/issue/12474 . To
avoid this, let's set `errors="replace"`, which tells the decoder
to replace invalid data with ? characters. This way we should get
as much of the output as can be read, and no crashes.
We also replace `universal_newlines=True` with `text=True` as
the latter is shorter, clearer, and what Python 3 subprocess
wants us to use, it considers `universal_newlines` to just be
a backwards-compatibility thing - "The universal_newlines argument
is equivalent to text and is provided for backwards compatibility"

This should make it possible to only import the library only when it's
really needed.
DNF does not work with libmodulemd v2. If we import libmodulemd2 and
then dnf, the program will just hang forever. We only need DNF in
pungi-gather, where libmodulemd is not needed, and also where we do need
libmodulemd, we don't have DNF.

This should make all tests pass on both Python 2 and Python 3.
Unittest2 is required on Py 2.6 and Py 3.

This should help with debugging by providing better information on which
Pungi version created the compose. In development, the version will show
output of git describe, in production it asks which version is installed
in site-packages/. The egg-info directory must be installed for this to
work.
It is no longer necessary to synchronize version in `setup.py` with
`pungi/__init__.py`.
