 rename t/unit-tests/{t-ctype.c => ctype.c} (71%)

In 'next' we use the if_test stuff to simplify the ctype unit tests.
This gives a good example to illustrate the strengths and weakness
of these approaches.  I resolved the conflict in 'seen' with this
topic in favor of clar tests so that it becomes easier to compare.

 #define TEST_CHAR_CLASS(class, string) do { \
 	size_t len = ARRAY_SIZE(string) - 1 + \
 		BUILD_ASSERT_OR_ZERO(ARRAY_SIZE(string) > 0) + \
 		BUILD_ASSERT_OR_ZERO(sizeof(string[0]) == sizeof(char)); \
-	int skip = test__run_begin(); \
-	if (!skip) { \
-		for (int i = 0; i < 256; i++) { \
-			if (!check_int(class(i), ==, !!memchr(string, i, len)))\
-				test_msg("      i: 0x%02x", i); \
-		} \
-		check(!class(EOF)); \
-	} \
-	test__run_end(!skip, TEST_LOCATION(), #class " works"); \
+	for (int i = 0; i < 256; i++) \
+		cl_assert_equal_i(class(i), !!memchr(string, i, len)); \
+	cl_assert(!class(EOF)); \
