lint: only skip 'unused' warnings after errors, not other warnings

Previously, in -w mode, any warning suppressed further 'unused'
warnings, even though there was no need to do that.  This can be seen in
the test gcc_attribute_var.c, where only the last unused variable from a
function was marked as unused, the others slipped through.

Fixed by counting the errors and the warnings separately and only
combining them if actually desired.

lint: fix check for declaration after statement in pre-C99 mode

The new code may not be the most beautiful, but it fixes all bugs that
occurred while testing message 327.  The grammar rules are taken from
C99 6.8.2, so it's no surprise they work well.

lint: properly name C99 in message about declaration after statement

Now that C99 has been released and published, there is no reason anymore
to refer to it as C9X.

lint: force each test to declare the expected diagnostics

By listing the expected diagnostics directly at the code that triggers
the diagnostics, it is easier to cross-check whether the diagnostics
make sense.

No functional change to lint itself.

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.
