tests/lint: remove .exp files, as they have become redundant

Now that each lint1 test lists all generated diagnostics as 'expect'
comments, the information from the .exp files is no longer needed.  The
only information that gets lost is the order of the diagnostics, which
is mostly relevant for paired messages like 'inconsistent definition' +
'previous definition was here'.

tests/lint: add more details to messages in msg_200 until msg_299

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

lint: fix null pointer dereference after syntax error

Found by afl, starting with the malformed input '/**/f=({;/**/};}' that
no longer crashes.  This input led to 'f=({L:;}', which is at least a
syntactically valid prefix of a translation unit, containing a GCC
statement expression with an unused label.  The error message for this
unused label assumed that it would always be inside a function
definition.

While here, document incomplete recovery after syntax errors, in
msg_249.c.

lint: warn about unreachable null statements

This warning flags the second semicolon of 'return;;' as being
unreachable.  It does not warn about these superfluous semicolons in
general though.

Seen in usr.bin/make/bmake_malloc.c.

lint: do not allow struct{const;}

In traditional C, a struct member was defined syntactically as
'type-specifier struct-declarator-list', the concept of a type-qualifier
was not known back then.

C90 invented the type-qualifier 'const' and relaxed the syntactic
requirement for struct member declarations by allowing 'const x'. Having
only a type-qualifier without an actual type may be regarded as an
"incomplete type", which would be forbidden by C90 and later.

Anyway, this doesn't occur in practice anyway, so there is no need for
lint to try to parse it.  This removes a bit of dead code, since a
type-qualifier-list can never have type struct or union.

lint: prefix error messages with 'error:'

This makes it easier to find these errors in the build logs.

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.
