[RFC v2 08/12] kunit: mock: add basic matchers and actions

[Daniel Latypov <dlatypov@google.com>]

From: Brendan Higgins <brendanhiggins@google.com>

Add basic matchers and actions needed for any kind of mocking to be
useful; these matchers and actions are how expectations for mocks are
described: what calls the mocks are expected to receive, and what the
mock should do under those circumstances.

+/**
+ * DOC: Built In Matchers
+ *
+ * These are the matchers that can be used when matching arguments in
+ * :c:func:`KUNIT_EXPECT_CALL` (more can be defined manually).
+ *
+ * For example, there's a matcher that matches any arguments:
+ *
+ * .. code-block:: c
+ *
+ *    struct mock_param_matcher *any(struct kunit *test);
+ *
+ * There are matchers for integers based on the binary condition:
+ *
+ * * eq: equals to
+ * * ne: not equal to
+ * * lt: less than
+ * * le: less than or equal to
+ * * gt: greater than
+ * * ge: greater than or equal to
+ *
+ * .. code-block:: c
+ *
+ *    struct mock_param_matcher *kunit_int_eq(struct kunit *test, int expected);
+ *    struct mock_param_matcher *kunit_int_ne(struct kunit *test, int expected);
+ *    struct mock_param_matcher *kunit_int_lt(struct kunit *test, int expected);
+ *    struct mock_param_matcher *kunit_int_le(struct kunit *test, int expected);
+ *    struct mock_param_matcher *kunit_int_gt(struct kunit *test, int expected);
+ *    struct mock_param_matcher *kunit_int_ge(struct kunit *test, int expected);
+ *
+ * For a detailed list, please see
+ * ``include/linux/mock.h``.
