ba0193ca28 gather: Add a hybrid depsolver backend
This patch adds a new gather method called `hybrid`, which uses a `fus`
binary, which must exist somewhere on the `$PATH`. It will call it
multiple times to add multilib packages.

The solver can handle packages, modules and comps groups as input.
However comps groups are never passed in. Pungi will expand it to a list
of packages to avoid issues with comps handling in fus. It ignores
optional packages, and if the group mentions a package that does not
exist, nothing else from the group is included.

Multilib is also handled outside of fus. Pungi will run it, parse the
packages from output, determines multilib packages and adds them as
input. Then it runs the solver again. This is done until nothing new is
added. Usually two passes should be enough.

Source packages and debuginfo are added as a final step. All debuginfo
packages from any included source are added. If the source or debuginfo
package is included in any lookaside repo, it will be skipped.

The tool expects to get a platform stream that should be provided for
modules to depend on. Pungi looks into the modules and gets the platform
from there. If there are more requests, an error is raised.

There is some missing functionality and options that are ignored.
Particularly these are:

 * gather_fulltree
 * gather_selfhosting
 * greedy_method

364d7f5229 Support multiple sources in one variant
With this patch the gather_source option is no longer used. Instead, all
sources are always used. If they return at least some input packages,
then a configured method is used and the returned lists of packages from
all sources are merged.

The method used for gathering can be configured for each variant and
gather source separately.

Additional packages are only added to the comps source.

Each gathering step is logged separately. All the logs are preserved for
later inspection.

ed22e07ef9 Port to Python 3
This should make all tests pass on both Python 2 and Python 3.

Unittest2 is required on Py 2.6 and Py 3.

c784dab4aa gather: Remove handling of impossible state
The get_system_release_packages function can never be called without a
variant, so it makes no sense to check for that condition.
