lint: fix handling of initializations
The implementation from March 2021 added proper support for designators
but didn't model the brace levels correctly. In particular, it could
not handle additional braces or omitted braces. In such a case, lint
skipped the remaining initializers from the initialization. Due to
this, type errors in the remaining initializers went unnoticed. Another
effect was that arrays of unknown size were wrongly reported as having
size 0.
Both GCC and Clang recommend placing braces around each sub-type that is
initialized, such as a struct, union or array. Postfix does not follow
these recommendations, therefore lint had to be disabled in
external/ibm-public/postfix/Makefile.inc. This commit fixes the bugs
mentioned there.

lint: remove unused message for struct without named members
Lint has not produced this message since the rewrite of the
initializations in March 2021. Structures that consist of only unnamed
bit-fields probably don't occur in practice.

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.
