Add basic support for the priority rules prefix. This patch does not
allow the utils to set or suggest priorities. It allows parsing and
retaining of the priority prefix if it already exists on rules and
checking if it's in the supported range.

This reverts commit 378519d23f8b6e55b1c0741e8cd197863e0ff8a0.
this commit was meant for the 2.13 branch not master

When dc010bc0340fe8b7159db5c3c2e01f7e27749ea8 was
backported to the apparmor-2.13 branch (in commit
75236d62e2bcbed36cccf84212d1ac92d2b6ae0b), it did not take into
account cb8c3377babfed4600446d1f60d53d8e2a581578, which creates the
common/list_af_names.sh script as used in the test case, was not also
backported to the apparmor-2.13 branch.
Change the test case to get the list of network AF names via the same
make invocation taken by the utils/vim/create-apparmor.vim.py script
before the common/list_af_names.sh existed.

... and self.pid which is also unused.
This simple change also means to adjust all the code that uses ReadLog.
We get rid of log_pid in aa.py, and have to change lots of test-*
The tools also have a list of network keywords, update it:
- add xdp and qipcrtr
- move ib and mpls to match the kernel order
Also add a test to ensure that (at least) the keywords provided by the
running kernel are listed in network_domain_keywords.
This parameter is always [], so we can simplify the ReadLog __init__()
parameters.
Note that some tests handed over '' instead of []. This was a bug, but
didn't matter because those tests only use a small portion of ReadLog.

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)
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)
This makes print()ing a class object much more helpful - instead of
<apparmor.rule.network.NetworkRule object at 0x7f416b239e48>
we now get something like
<NetworkRule> network inet stream,
(based on get_raw())
A NetworkRuleset will be printed as (also based on get_raw())
<NetworkRuleset>
network inet stream,
allow network inet stream, # comment
</NetworkRuleset>
Also add tests to test-network.py to ensure that __repr__() works as
expected.

Thanks to a bug in the apparmor.d manpage, NetworkRule rejected rules
that contained only TYPE (for example "network stream,"). A bugreport on
IRC and some testing with the parser showed that this is actually
allowed, so NetworkRule should of course allow it.
Note: not strip()ing rule_details is the easiest way to ensure we have
whitespace in front of the TYPE in TYPE-only rules, which is needed by
the RE_NETWORK_DETAILS regex.
Also adjust the tests to the correct behaviour.

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.

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().

Add utils/test/test-network.py with tests for NetworkRule and
NetworkRuleset.
The tests are hopefully self-explaining, so let me just mention the most
important things:
- I started to play with namedtuple, which looks very useful (see "exp")
- the test loops make the tests much more readable (compare with
test-capability.py!) and make it easy to add some more tests
- 100% coverage :-)
