rillig | lint: handle __attribute__((__unused__)) for functions and variables
Previously, lint ignored the '__unused' marker, requiring its own /* ARGSUSED */ marker instead.
Previously, attributes were interpreted as soon as the closing parenthesis was parsed. For a function definition such as '__unused static void f(void) {}', this was too early, as the attribute was not connected to the function, as the function was not parsed yet.
Now, the 'unused' attribute is passed around by the parser, until it is merged into the declarator where it belongs. Due to an inaccuracy in the grammar, the 'used' attribute has to be passed through a parameter_list, even though a parameter list is not related to attributes. Still, it's better than before.

rillig | lint: warn about function definitions without header declaration
The existing warning was only issued for function declarations, not for function definitions.
The interesting change in the tests is in msg_351.c. Many other tests use non-static functions due to their syntactic brevity. In these tests, the warning is disabled individually, to allow new functions to be added without generating warning 351.

Add some tests that were previously empty. Some other tests are still empty.

rillig | lint: remove message 189, add tests for a few other messages
Message 189 would have applied to traditional C and was supposed to detect assignments between struct and union types. The corresponding check had never been implemented though.
Traditional C has been superseded for 30 years now, therefore there is no point in adding this check retroactively.

rillig | lint: add a test for each message produced by lint1
Having a test for each message ensures that upcoming refactorings don't break the basic functionality. Adding the tests will also discover previously unknown bugs in lint.
The tests ensure that every lint message can actually be triggered, and they demonstrate how to do so. Having a separate file for each test leaves enough space for documenting historical anecdotes, rationale or edge cases, keeping them away from the source code.
The interesting details of this commit are in Makefile and t_integration.sh. All other files are just auto-generated.
When running the tests as part of ATF, they are packed together as a single test case. Conceptually, it would have been better to have each test as a separate test case, but ATF quickly becomes very slow as soon as a test program defines too many test cases, and 50 is already too many. The time complexity is O(n^2), not O(n) as one would expect. It's the same problem as in tests/usr.bin/make, which has over 300 test cases as well.
