There is now a single option `multilib`, that maps variants and arches
to multilib methods. This replaces old `multilib_methods` option.
Multilib arches are implicitly deduced instead of using the
`multilib_arches` option.
The test compose is updated to only enable multilib on Server and its
addons.

On case-insensitive filesystems it is not such a good idea to have
directories that only differ in case. Packages should be always split
into lowercased directories.
The test data is modified to include some packages starting with
uppercase letters. The example in code can be verified by running
`nosetests --with-doctest`.
