/run/systemd/journal/dev-log, so this access is now required in the base

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
error message to make it usable everywhere.
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).
v2:
- remove check_allow_deny and check_audit parameters from
is_covered_localvars()

If one of the testcases fail, this goes unnoticed in "make coverage".
This patch changes the Makefile so that test failures let
"make coverage" fail.
You can use make COVERAGE_IGNORE_FAILURES=true coverage to build
coverage data even if some tests fail.

For reasons that are unclear, python's setuptools doesn't install

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.

This patch integrated the new capability rule class into aa.py and
cleanprof.py.
Patch changes:
v6:
- fix logic around same_file in cleanprofile.py that was causing
capabilities to be deleted when they weren't covered by an
abstraction.
v5:
- merge my changes into Christian's original patches
- use CapabilityRule.parse() for parsing raw capability rules and
getting a CapabilityRule instance back
- cope with move of parse_modifiers back into rule/__init__.py.

This patch adds four classes - two "base" classes and two specific for
capabilities:
utils/apparmor/rule/__init__.py:
class base_rule(object):
Base class to handle and store a single rule
class base_rules(object):
Base class to handle and store a collection of rules
utils/apparmor/rule/capability.py:
class capability_rule(base_rule):
Class to handle and store a single capability rule
class capability_rules(base_rules):
Class to handle and store a collection of capability rules
Changes:
v5:
- flattened my changes into Christian's patches
- pull parse_modifiers into rule/__init__.py
- pull parse_capability into rule/capability.py
- make CapabiltyRule.parse() be the class/static method for parsing
raw capability rules.
- parse_capability: renamed inlinecomment and rawrule to comment
and raw_rule to be consistent with CapabilityRule fields.

This patch restricts MS_REC to only be used while defining the MS_RBIND,
MS_RUNBINDABLE, MS_RPRIVATE, MS_RSLAVE, and MS_RSHARED macros.
The MS_R* macros are simply an OR of the corresponding non-recursive
macro and MS_REC:
#define MS_RBIND (MS_BIND | MS_REC)
Previously, a shortcut was taken when needing to specify the
non-recursive and recursive macros:
(MS_BIND | MS_UNBINDABLE | MS_PRIVATE | MS_SLAVE | MS_SHARED | MS_REC)
By using MS_REC above, it is not immediately clear that
MS_R{BIND,UNBINDABLE,PRIVATE,SLAVE,SHARED} are also included.
By restricting the use of MS_REC, this patch improves readability by
forcing the use of the MS_R{BIND,UNBINDABLE,PRIVATE,SLAVE,SHARED} macros
instead of relying on the MS_REC shortcut.

The parser correctly rejects mount make-* options (make-shared,
make-slave, make-private, make-unbindable) when a device is specified
(the source argument of mount(2)). However, it was not rejecting the
recursive make-* options (make-rshared, make-rslave, make-rprivate,
make-runbindable) when a device was specified.
This patch adds the MS_REC bit, which is used to indicate a recursive
option, to the MS_CMDS macro. Without this change, the recursive options
are treated as normal mount options.

The parser should not indicate success when mount rules contain
unknown mount options:

$ echo $?

This patch modifies the parser so that it prints an error message and
exits with 1:
$ echo "/t { mount options=(XXX) -> **, }" | apparmor_parser -qQ
unsupported mount options

There are a number of differences between what the apparmor.d(5) man
page lists as valid AppArmor mount rule options and what apparmor_parser
looks for when parsing mount rules. There are also typos in the man page
and parser around mount options. Here's the breakdown of problems and
fixes made in this patch:
* The apparmor.d(5) man page improperly documented a "nodirsync"
option.
- That mount option does not exist and the parser did not honor it.
Remove the mention from the apparmor.d(5) man page.
* The loud option was typoed as "load" in both the man page and parser
- There's no sense in preserving backwards compatibility. "load" is
simply wrong and should not be honored. The man page and parser are
updated to only use "loud".
* The rbind option wasn't listed in the man page.
- Add rbind to the man page. No change needed for the parser.
* The documented unbindable, private, slave, and shared options were
not correctly parsed. The parser expected
make-{unbindable,private,slave,shared}.
- The parser is updated to accept both the documented
{unbindable,private,slave,shared} options and their variants
prefixed with "make-". The man page will not document the "make-"
variants.
* The recursive {runbindable,rprivate,rslave,rshared} options were not
documented and were only recognized by the parser if they were
prefixed with "make-".
- The man page is updated to document the option strings that are not
prefixed with "make-". The parser still accepts the "make-"
variants.
* The man page documented a "rec" option but the parser didn't honor
it. The MS_REC macro is used by the mount utility to be bitwise OR'ed
with MS_{UNBINDABLE,PRIVATE,SLAVE,SHARED} to indicate the
corresponding recursive mount options.
- This is not an option that should be exposed in the AppArmor policy
since we already allow have the
{runbindable,rprivate,rslave,rshared} options.
* The man page typoed the {no,}relatime options as {no,}relative.
- The man page is updated to document the correct option strings. The
parser requires no change.

LOG_MODE_RE (used in validate_log_mode() in aamode.py) just checked if
the given parameter contains one of the possible matches. This resulted
in "invalid" being a valid log mode (from audit.log requested_mask or
denied_mask) because it contains 'a', which is a valid file mode.
This patch wraps the regex into ^(...)+$ to make sure the full
string contains only allowed file modes.
The patch also adds some tests for validate_log_mode().
