It then determines the length of the string before this sequence, and strips that number of characters off the beginning of the following lines until the last KUnit output line is reached. These fixes have been tested with additional tests in the KUnitParseTest and their associated logs have also been added.

Two new methods have been added to kunit_kernel: make_allyesconfig and run_allconfig. Firstly, if --alltests is specified, kunit.py triggers build_um_kernel which sets jobs to the max number of cpus on the user's computer. This is done to shorten the long running time it takes to build and start a kernel with all configs enabled. It then calls the make command, disables the broken configs that would otherwise prevent UML from building, then starts the kernel with all possible configurations enabled. All stdout and stderr is sent to test.log and read from there then fed through kunit_parser to parse the tests to the user. Also added a signal_handler to clean the config in case kunit is interrupted while running. Tested: Run under different conditions such as testing with --raw_output, testing program interrupt then immediately running kunit again without --alltests and making sure to clean the configs. Formal unit tests will be submitted in a future patchset.
