As discussed a while ago, switch the utils (including their tests) to
use python3 by default. While on it, drop usage of "env" to always get
the system python3 instead of a random one that happens to live
somewhere in $PATH.
In practise, this patch doesn't change much - AFAIK openSUSE, Debian and
Ubuntu already patch aa-* to use python3.
Also add a note to README to officially deprecate Python 2.x.
(I won't break Python 2.x support intentionally - unless some future
change gives me a very good reason to finally drop Python 2.x support.)

(since 2016-08-23, but the commit had to wait for the FileRule series
because it touches test-file.py)
This means adding
- self.can_edit - True if editing via '(N)ew' should be possible (will
be False for bare file rules)
- edit_header() - returns the prompt text and the current path
- validate_edit() - checks if the new path matches the original one
- store_edit() - changes the path to the new one (even if it doesn't
match the old one)
self.can_edit and the 3 functions are also added to BaseRule:
- can_edit is False by default
- the functions raise a NotImplementedError
Also add tests for the added code.

File rules contain some optional details (like leading permissions and
the file keyword) which should be ignored in non-strict mode.
This patch passes through the 'strict' parameter to is_equal_localvars
and adds it as function parameter in all existing rule classes.
It also adjusts test-baserule.py to test with the additional parameter.

As Kshitij mentioned, abstract methods should use NotImplementedError
instead of AppArmorBug.
While changing this, I noticed that __repr__() needs to be robust against
NotImplementedError because get_raw() is not available in BaseRule.
Therefore the patch changes __repr__() to catch NotImplementedError.
Of course the change to NotImplementedError also needs several
adjustments in the tests.

(long before branching off 2.10, therefore I'll also commit to 2.10)
BaseRule:
- add logprof_header() - sets the 'Qualifier' (audit, allow/deny) header
if a qualifier is specified, calls logprof_header_localvars() and then
returns an array of headers to display in aa-logprof and aa-mergeprof
- add logprof_header_localvars() - dummy function that needs to be
implemented in the child classes
NetworkRule: add logprof_header_localvars() - adds 'Network Family'
and 'Socket Type' to the headers
CapabilityRule: add logprof_header_localvars() - adds 'Capability' to
the headers
Also change aa-mergeprof to use rule_obj.logprof_header() for network
and capability rules. This means deleting lots of lines (that moved to
the *Rule classes) and also deleting the last differences between
capabiltiy and network rules.
Finally add tests for the newly added functions.

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 ;-)
