Pull kunit updates from Shuah Khan:

- add support for running Rust documentation tests as KUnit tests

- make init, str, sync, types doctests compilable/testable

- add support for attributes API which include speed, modules
attributes, ability to filter and report attributes

- add support for marking tests slow using attributes API

- add attributes API documentation

- fix a wild-memory-access bug in kunit_filter_suites() and a possible
memory leak in kunit_filter_suites()

- add support for counting number of test suites in a module, list
action to kunit test modules, and test filtering on module tests

kunit: Add ability to filter attributes

Add filtering of test attributes. Users can filter tests using the
module_param called "filter".

Filters are imputed in the format: <attribute_name><operatio

kunit: Add ability to filter attributes

Add filtering of test attributes. Users can filter tests using the
module_param called "filter".

Filters are imputed in the format: <attribute_name><operation><value>

Example: kunit.filter="speed>slow"

Operations include: >, <, >=, <=, !=, and =. These operations will act the
same for attributes of the same type but may not between types.

Note multiple filters can be inputted by separating them with a comma.
Example: kunit.filter="speed=slow, module!=example"

Since both suites and test cases can have attributes, there may be
conflicts. The process of filtering follows these rules:
- Filtering always operates at a per-test level.
- If a test has an attribute set, then the test's value is filtered on.
- Otherwise, the value falls back to the suite's value.
- If neither are set, the attribute has a global "default" value, which
is used.

Filtered tests will not be run or show in output. The tests can instead be
skipped using the configurable option "kunit.filter_action=skip".

Note the default settings for running tests remains unfiltered.

Finally, add "filter" methods for the speed and module attributes to parse
and compare attribute values.

Note this filtering functionality will be added to kunit.py in the next
patch.

kunit: Add test attributes API structure

Add the basic structure of the test attribute API to KUnit, which can be
used to save and access test associated data.

Add attributes.c and attributes.h to hold associated structs and functions
for the API.

Create a struct that holds a variety of associated helper functions for
each test attribute. These helper functions will be used to get the
attribute value, convert the value to a string, and filter based on the
value. This struct is flexible by design to allow for attributes of
numerous types and contexts.

Add a method to print test attributes in the format of "# [<test_name if
not suite>.]<attribute_name>: <attribute_value>".

Example for a suite: "# speed: slow"

Example for a test case: "# test_case.speed: very_slow"

Use this method to report attributes in the KTAP output (KTAP spec:
https://docs.kernel.org/dev-tools/ktap.html) and _list_tests output when
kernel's new kunit.action=list_attr option is used. Note this is derivative
of the kunit.action=list option.

In test.h, add fields and associated helper functions to test cases and
suites to hold user-inputted test attributes.
