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"

We no longer need to support Python 2, so there's no point in this
compatibility layer.

The library is imported if available, but we never build it in any
environment where the package would be installed. It was last used for
RHEL 6 builds.

Pungi can use either genisoimage or xorriso to create ISOs.
It also needed isoinfo utility for querying volume ID from the ISO
image. However, the utility is part of the genisoimage suite of tools.
On systems that no longer provide genisoimage, the image would be
successfully generate with xorriso, but then pungi would fail to extract
the volume id leading to metadata with missing values.

When partial cleanup messes up the guestfs cache, the call to guestmount
will fail. To fix that, let's check if there is a problem first and
clean up everything if needed.

We can use a key function instead of relying to the deprecated cmp. This
makes the code work on Python 2.6 and on recent versions it makes it
faster.

This will automatically convert the output to unicode/str and we will
not have to worry about decoding ourselves.

Occasionally we have seen the mount command fail. The default error
message says to set some environment variables and try again. We can
just always set the environment and only print the output on failure.

This patch refactors logic for creating a temporary mount point,
mounting an image, running arbitrary code on it, unmounting the image
and removing the mount point. It immediately uses it in the buildinstall
phase.
Similar mounting is present in product_img phase as well, but due to
different usage pattern it's not changed yet.

If the checkisomd5 command exits successfully but returns a wrong value,
we should catch and log that. In theory this should be impossible, but
we have seen it in production.
