2019-09-30kunit: test: add the concept of expectationsBrendan Higgins
Add support for expectations, which allow properties to be specified and then verified in tests.

2019-09-30kunit: test: add assertion printing libraryBrendan Higgins
Add `struct kunit_assert` and friends which provide a structured way to capture data from an expectation or an assertion (introduced later in the series) so that it may be printed out in the event of a failure.

2019-09-30kunit: test: add string_stream a std::stream like string builderBrendan Higgins
A number of test features need to do pretty complicated string printing where it may not be possible to rely on a single preallocated string with parameters. So provide a library for constructing the string as you go similar to C++'s std::string. string_stream is really just a string builder, nothing more.

2019-09-30kunit: test: add test resource management APIBrendan Higgins
Create a common API for test managed resources like memory and test objects. A lot of times a test will want to set up infrastructure to be used in test cases; this could be anything from just wanting to allocate some memory to setting up a driver stack; this defines facilities for creating "test resources" which are managed by the test infrastructure and are automatically cleaned up at the conclusion of the test.

2019-09-30kunit: test: add KUnit test runner coreBrendan Higgins
Add core facilities for defining unit tests; this provides a common way to define test cases, functions that execute code which is under test and determine whether the code under test behaves as expected; this also provides a way to group together related test cases in test suites (here we call them test_modules). Just define test cases and how to execute them for now; setting expectations on code will be defined later.
