aa_test.py doesn't run in 'make check' because its filename doesn't
match the 'test-*.py' pattern.
Move tests for globbing ("plain" globbing and globbing with ext) to
test-aare.py to make sure those tests actually run.
Note: This isn't an exact move - I adjusted some of the tests to make
them more useful, and added some more tests.
Also, glob_path() and glob_path_withext() no longer exist in aa.py.
They moved to the AARE class as part of the FileRule patch series.

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)
When matching an AARE against another AARE, most AARE objects don't
contain orig_regex (only AARE instances originating from a log event
contain orig_regex).
In this case, match() will use is_equal() to error out on the safe side.
Unfortunately this also means that there are lots of false negative
cases where match() returns False errornously.
With this patch, match() checks the given AARE regex and, if it doesn't
contain any special characters (wildcards, alternations or variables),
handles it as plain path. This avoids most of the false negatives.
Also extend the AARE tests to check a bunch of plain path regexes using
AARE matching instead of only str matching.

glob_path() and glob_path_ext() modify a (path) regex, so move them to
AARE. Also change them to use self.regex instead of the newpath
parameter, and to return a new AARE object.
While on it, also add several tests to test-aare.py.
Note: There are still glob_path() and glob_path_ext() calls in aa.py,
but those calls are in a (since the middle of this patch series) dead
code section. pyflakes will complain about them nevertheless ;-)

Thanks to http://bugs.python.org/issue10076, we need to implement this
ourself :-/
Also add some tests to ensure __deepcopy__() works as expected.
I found this bug while testing the dbus patch series, which crashed
aa-cleanprof with
TypeError: cannot deepcopy this pattern object

The AARE class is meant to handle the internals of path AppArmor regexes
at various places / rule types (filename, signal peer etc.). The goal is
to use it in rule classes to hide all regex magic, so that the rule
class can just use the match() method.
If log_event is given (which means handing over a raw path, not a regex),
the given path is converted to a regex in convert_expression_to_aare().
(Also, the raw path is used in match().)
BTW: The reason for delaying re.compile to match() is performance - I'd
guess a logprof run calls match() only for profiles with existing log
events, so we can save 90% of the re.compile() calls.
The patch also includes several tests.

With this addition, all globbing styles (as documented in apparmor.d(5))
are covered in the convert_regexp() tests.
Acked-by: Seth Arnold <seth.arnold@canonical.com>
The tests for convert_regexp() were hidden in common_test.py, where they
were never executed.
This patch moves them to the new file test-aare.py and also converts the
regex_tests.ini to a tests[] array to have the test data inside the test
file. (All tests from regex_tests.ini are in test-aare.py, and two tests
with prepended and appended path segments were added.)
Also add some tests that check the raw behaviour of convert_regexp() -
the tests "by example" are probably more useful and for sure more
readable ;-) but I want to have some examples of the converted regexes
available.
