Functions abstracting the distribution are not only needed in the
context of the distro subcommand, but also by other code, so make the
bulk of the code abstracting the distribution available in some place
more universally useful than below cmds.distro.
This commit leaves the source files mostly unchanged. They are only
patched to fix import paths, so that functionality is preserved.
Refactoring the code from command-line API to library API will be
done by the next commit.

--fix-broken is added to apt-get options in non-interactive mode, but
seems to work only with apt-get install, not with apt-get update.
Don't add it at all for now.

Add more methods, to make Package more useful:
- __repr__()
- Class-mMethods to help with parsing of strings gathered from the

parse_spec_str()
parse_specs_str()

Most run_xxx() return stdout and stderr. There's no way, really, for
the caller to get hold of the exit code of the spawned executable. It
can pass throw=true, catch, and assume a non-zero exit status. But
that's not semantically clean, since the spawned function can well be
a test function which is expected to return a non-zero status code,
and the caller might be interested in what code that was, exactly.
The clearest way to solve this is to return the exit code as well.
This commit does that.

get-os.sh returned "suse" for SuSE-like distros, and that seems more
appropriate since SLES is not OpenSUSE but should share and ID with
other SuSE variants.

App.distro_id used to return "opensuse-tumbleweed", analogous to
what's in ID@/etc/os-release, but now returns "opensuse", and the
"tumbleweed" goes into "codename". That matches more what Debian-like
distributions do, but it confuses _backend_path. Adapt it to map the
new distro_id correctly.

This is a code maintenance commit: some run_xxx() helper functions
take a string, some a list, and some just digest all arguments and
pass them on as a list to exec() to be executed. That's highly
inconsistent. This commit changes that to list-only.
Except for the run_cmd() method of SSHClient, which is still run as a
shell method, because, erm, it's a shell. Might be changed in the
future for consistency reasons.

Rename jw.pkg.cmds.distro.backend.BackendCmd to Backend, because it's
not necessarily a command, i.e. doesn't necessarily have a run()
method. It's more of a distribution abstraction of the steps needed
for for a specific command, the run() method itself is implemented in
jw.pkg.cmds.distro.CmdXxx.
This commit is the beginning of a bigger move to change the
distribution backend class hierarchy. At the end of this change set,
the backend command should not derive the backend classes from a base
specific to the respective distribution, but from an abstract base
class specific to the command run. The distribution specifics are
then going to be encapsulated in another class called "Util", an
instance of which is going to be provided to the backend as .util
member.

Move the body of BackendCmd.sudo() into a function. The rationale
behind that is that its functionality is independent of the calling
object for the most part, so having it in a function instead of a
method is the more modular pattern.

apt-get install suggests it wants to be called with -f to clean up
some mess left behind from a previous install. Adding -f in the hope
add it to the install options by default. OTOH, it wants to be called
that without arguments, not sure if always passing it along is a good
idea.
The man page says:
-f, --fix-broken
Fix; attempt to correct a system with broken dependencies in
place. This option, when used with install/remove, can omit any
packages to permit APT to deduce a likely solution. If packages
are specified, these have to completely correct the problem. The
option is sometimes necessary when running APT for the first time;
APT itself does not allow broken package dependencies to exist on
a system. It is possible that a system's dependency structure can
be so corrupt as to require manual intervention (which usually
means using dpkg --remove to eliminate some of the offending
packages). Use of this option together with -m may produce an
error in some situations. Configuration Item:
APT::Get::Fix-Broken.
Also turn the short options -yq into long options --yes --quiet for
more obvious debugging if something goes awry.

Prepending --login to the argument list of BackendCmd.sudo() fails if
run as root, because BackendCmd.sudo() detects that and leaves the
/usr/bin/sudo out from the exec call. Fix that by adding an
opts: list[str] parameter to sudo, defaulting to an empty list, with
options that should be passed to /usr/bin/sudo.
