- add_inc_ie() stores include and include if exists rules
- get_clean() and get_raw() return the profile preamble (currently only
the include rules)
Also add tests for the new functions.
Add some tests with the complex profile name (including alternations and
wildcards) to ensure we don't break such cases in the future.
These tests are based on the log from the (invalid) bugreport
https://gitlab.com/apparmor/apparmor/issues/26
ProfileList is meant to store the list of profiles (both name and
attachment) and in which files they live.
Also add unittests to make sure everything works as expected.
