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'.

lint: in C99 mode, make implicit function declarations an error

In tree.c 1.294 from 2021-06-28, I had already tried this, but at that
time, there were too many implicit function definitions in the NetBSD
tree.  Most of them were GCC builtins, which lint did not recognize.
Therefore I had to revert to a warning in tree.c 1.302 from 2021-06-30.

In the meantime, lint has learnt to recognize compiler builtins, see
is_compiler_builtin, so try again now.  The build logs from x86_64,
i386, sparc and sparc64 show no more implicit function declarations.

lint: in C99 mode, only warn about implicit function declarations

Since tree.c 1.294 from 2021-06-28 (two days ago), lint errored out on
an implicit function declaration.  In principle it is correct to do so
since C99 requires it, but in practice there are a several functions
that are not declared in the translation unit itself since they are
provided by the compiler.  Typical examples for GCC and Clang are the
various functions named '__builtin_*' and '__atomic_*'.

For now, only warn about these but don't error out.

lint: mention the name of an implicitly declared function

In the regular NetBSD builds, this happened in swab.c:65.  That line
contains __predict_false, which may or may not be a macro.  In other
cases, there may be more than one function call in a single line.

"remove implicit function declaration".

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.
