Makes use simpler. The setools submodules map 1:1 to classes anyway;
the separate modules are simply to ease organization.
Change seinfo to use conditional setter use rather than conditional
instantiation of queries. Note: pylint disable is added because pylint
gets confused by the reuse of the q variable and thinks that q is always
BoolQuery, so it incorrectly reports missing member functions.
Not comprehensive yet. Only planning to do setools pkg (not policyrep),
with the exception being the SELinuxPolicy class in policyrep.
Avoids performance-critical paths. Use only info and debug so in normal
cases the user only sees messages if they ask for it (e.g. -v).
Catch all exceptions in the main bulk of the CLI code. We can't do anything
if there is an exception, so either print the error message from the
exception, or print the traceback if debug is enabled.
