severity() will, surprise!, return the severity of a rule, or
sev_db.NOT_IMPLEMENTED if a *Rule class doesn't implement the severity()
function.
Also add the NOT_IMPLEMENTED constant to severity.py, and a test to
test-baserule.py that checks the return value in BaseRule.

Add match() and _match() class methods to rule classes:
- _match() returns a regex match object for the given raw_rule
- match() converts the _match() result to True or False
The primary usage is to get an answer to the question "is this raw_rule
your job?". (For a moment, I thought about naming the function
*Rule.myjob() instead of *Rule.match() ;-)
My next patch will change aa.py to use *Rule.match() instead of directly
using RE_*, which will make the import list much shorter and hide
another implementation detail inside the rule classes.
Also change _parse() to use _match() instead of the regex, and add some
tests for match() and _match().

test_parse_modifiers_invalid() uses a hand-broken ;-) regex to parse
only the allow/deny/audit keywords. This test applies to all rule types
and doesn't contain anything specific to capability or other rules,
therefore it should live in test-baserule.py
Moving that test also means to move the imports for parse_modifiers and
re around (nothing else in test-capability.py needs them).

Add some tests for the Baserule class to cover the 3 functions that must
be re-implemented in each rule class. This means we finally get 100%
test coverage for apparmor/rule/__init__.py ;-)
