lib/list-test: add a test for the 'list' doubly linked list
Add a KUnit test for the kernel doubly linked list implementation in include/linux/list.h Each test case (list_test_x) is focused on testing the behaviour of the list function/macro 'x'. None of the tests pass invalid lists to these macros, and so should behave identically with DEBUG_LIST enabled and disabled. Note that, at present, it only tests the list_ types (not the singly-linked hlist_), and does not yet test all of the list_for_each_entry* macros (and some related things like list_prepare_entry). Ignoring checkpatch.pl spurious errors related to its handling of for_each and other list macros. checkpatch.pl expects anything with for_each in its name to be a loop and expects that the open brace is placed on the same line as for a for loop. In this case, test case naming scheme includes name of the macro it is testing, which results in the spurious errors.
