serialize_profile_from_old_profile() in aa.py, as a preparation to add
tests and then switch to the upcoming RE_PROFILE_START wrapper function.
Besides moving the code, I replaced write_prof_data[profile][hat]['profile']
and write_prof_data[profile][hat]['external'] with function parameters
to avoid that I have to pass around the full write_prof_data.
Note: The "lineno" parameter is technically superfluous - I kept it to
have the parameters as close to parse_profile_start() as possible and
hope that I can merge those functions later (when we have test coverage).

Also add a comment to act() that it's only used by aa-cleanprof.
Note: The new functions add the --base parameter to the apparmor_parser
calls, which also means the disable directory inside the given profile
dir (and not always /etc/apparmor.d/disable) is now honored.

logparser.py / add_event_to_tree() has 5 places to handle 'path' events.
This patch merges most if conditions to reduce that to 2 places.
It also makes the matching a bit more strict - instead of using 'in',
'xattr' has to be an exact match and 'file_' is matched with startswith().
Also, 'getattr' is added to the list of file events.

aa-status was crashing when parsing through /proc/mounts looking to see
if and where the securityfs synthetic file system is mounted if there
was a mount point that contained characters outside of the charset in
use in the environment of aa-status. This patch fixes the issue by
converting the read of /proc/mounts into a binary read and then uses
decode on the elements.

The upcoming function parse_profile_start() (which is a wrapper around
the updated RE_PROFILE_START, and will live in regex.py) needs
strip_profile(), but importing it from aa.py fails with an import loop.
Therefore this patch moves strip_quotes() from aa.py to regex.py and
re-imports it into aa.py.
As a bonus, the patch also adds some tests for strip_quotes() ;-)
Also add TestStripQuotes to the test_suite list because it won't run
otherwise.

Move the code for parsing the profile start ("/foo {") from aa.py
parse_profile_data() to a separate function parse_profile_start().
Most of the changes are just moving around code, with some small
exceptions:
- instead of handing over profile_data to parse_profile_start() to
modify it, it sets two variables (pps_set_profile and
pps_set_hat_external) as part of its return value, which are then
used in parse_profile_data() to set the flags in profile_data.
- existing_profiles[profile] = file is executed later, which means
it used the strip_quotes() version of profile now
- whitespace / tab level changes
The patch also adds some tests for the parse_profile_start() function.

Also adds a check to get_profile_flags() to catch an invalid syntax:
/foo ( ) {
was accepted by get_profile_flags, while
/foo () {
failed.
When testing with the parser, both result in a syntax error, therefore
the patch makes sure it also fails in get_profile_flags().

This means that aa-logprof will ignore the event instead of crashing with
AppArmorException: 'Unexpected rank input: var/run/nscd/passwd'
Note that I made the check as specific as possible to be sure it doesn't
hide other events.

Make sure most tools (for example aa-complain) don't error out if
no logfile can be found. (For obvious reasons, aa-logprof and
aa-genprof will still require a logfile ;-)
This is done by moving code from the global area in aa.py to the new
function set_logfile(), which is called by aa-logprof and aa-genprof.
While on it,
- rename apparmor.filename to apparmor.logfile
- move the error handling for user-specified logfile from aa-genprof
and aa-logprof to aa.py set_logfile()
Note: I'd have prefered to hand over the logfile as parameter to
do_logprof_pass(), but that would break last_audit_entry_time() in
aa-genprof which requires the log filename before do_logprof_pass()
is called.

Split is_covered() in capability.py into
- is_covered_localparts() for rule-specific code
- is_covered() for common code - located in __init__.py
The object type comparison now uses type(self) and a slightly different

Also rename rule_obj to other_rule which is more self-explaining
(inspired by the parameter name in the is_covered() dummy in __init__.py).

adds some tests for severity.py and improves the test coverage to
nearly 100% (only 3 partial left).
Added tests and details (all in SeverityVarsTest):
- move writing the tunables file from setUp() into _init_tunables() for
more flexibility (allows to specify other file content)
- test adding to a variable (+=)
- test #include
- make sure double definition of a variable fails
- make sure redefinition of non-existing variable fails
BTW: even the comment added to VARIABLE_DEFINITIONS contributes to
the coverage ;-)
severity.py passes all added tests, however I should note that including
a non-existing file is silently ignored.
