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: fix memory corruption in statement expressions (since 2021-12-17)

The commit that introduced the assertion failure looks innocent, it only
adds a few predefined functions for GCC mode.  Nevertheless, before that
commit, lint consistently complained about 'error: void type illegal in
expression [109]', which doesn't make sense either.

This fix also removes the creative use of the initialization stack to
store the type of the statement expression.  Having a separate stack for
these statement expressions makes the code easier to understand.

tests/lint: remove duplicate platform, generate platforms list

It was an unreliable idea to extract the platform properties from the
targparam.h files manually, even if it was a one-time job. I still made
a mistake by accidentally marking aarch64 as schar, even though it is
uchar, plus I duplicated the line for powerpc64.

Remove the duplicate line, no functional change.

tests/lint: add tests for platform characteristics

Running lint in usr.bin/make on i386 fails due to this warning:

cond.c(800): warning: argument #3 is converted from 'unsigned char' to
    'unsigned int' due to prototype [259]

This warning only occurred on i386 but not on sparc or x86_64. Try to
reproduce the test situation in platform_int.

The platform code in t_integration.sh was not strict enough, it didn't
check for multiple conditions, such as in msg_132_ilp32. That test was
only supposed to run on ILP32 platforms where size_t is unsigned int. It
also ran on sparc, even though size_t is long there.

tests/lint: guard against typos in test environment configuration

Some tests had "lint1-only-if" without a trailing colon, others included
the trailing colon.  The tests that included the trailing colon were run
even though they were supposed to be skipped, and they failed, as could
be expected.

To prevent further typos, always require the trailing colon, just as in
"lint1-flags" and fail fast on unknown "lint1" comments.

tests/lint: rework ATF test driver

To skip tests that work only on particular platforms, a simple 'eval'
from the shell does not work since it does not exit on failure.  Fix
this by storing the commands in a local variable first.

Remove configuration knobs 'lint1-only-if-arch' and 'lint1-skip-if-arch'
since they are unused.

When skipping a test, actually mark it as skipped in the ATF statistics.

tests/lint: add test that only runs where char == unsigned char

There a 4 regular NetBSD builds where lint is activated.  All these
builds run on platforms where char == signed char.

The official test runs from https://releng.netbsd.org/test-results.html
mostly have char == signed char as well.

However, lint behaves differently on platforms with char == unsigned
char.  On these platforms, a simple "char ch = '\xff'" leads to the
bogus warning that "conversion of 'int' to 'char' is out of range".

tests/lint: add tests for ILP32 platforms

Previously, all tests for lint had to produce the exact same output, no
matter which platform they ran on.  This differs from practical needs
since lint is intended to produce different results depending on whether
the platform is ILP32 or LP64.

Examples for these are type conversions and the widths of the integer
types during lexical analysis.

tests/lint: remove list of test names from t_integration

By convention, each *.c file in the source directory is a test case.

There is no need to list them individually and redundantly.

There is also no need to group the tests for the individual messages.
This ensures that each test is run in the regular builds.  Previously,
the test all_messages stopped after the first failure.

lint: require C11 for _Generic

This does not have any effect in practice since the option -g
(originally meant for GCC extensions to the C standards) implicitly
allows all features from C11, since err.c 1.111 from 2021-04-14.

Since the default lint flags for NetBSD builds include the option -g,
this allows all C11 features.

Currently it is not possible to say "allow GNU extensions but not C11".

lint: fix option -Ac11, add test for _Generic

Previously, selecting the option -Ac11 allowed features from C11 but at
the same time prohibited 'long long', which was added in C99.  This was
caused by the option -s, which is interpreted as "allow features from
C90, but no later".

The test for _Generic, which has been added in C11, demonstrates that
the current implementation is broken.  Lint currently thinks that the
return type of a _Generic selection is the type of the expression, but
it really is the type of the selected expression.  In the current tests,
this is always 'const char *', but C11 does not require that the types
of a generic selection are compatible.

tests/lint: allow skipping individual tests

Depending on the platform, some tests do not make sense or produce
platform-dependent results.  Allow these tests to be marked as such.

For example, the test lex_integer.c only works on 64-bit platforms.
Therefore it is disabled on i386 for now since it prints different
warnings there.  Even better would be a "lint1-only-on-lpi32" toggle,
but that would need detection of 'sizeof(int)' at runtime.

Previously, declaring a bit-field of type plain 'int' resulted in this

lint: in code from included files, print stack trace

Previously, the standard NetBSD build generated several lint warnings in
lhash.h from OpenSSL, without providing any hint as to which file
actually included that header.  In cases like these, lint now interprets
the line number information in the preprocessor output from GCC to
reconstruct the exact include path to the file in question.

The program check-expect.lua had to be rewritten almost completely since
it assumed that all diagnostics would come from the main file.  In all
existing tests, this was true, but these tests did not cover all cases
that occurred in practice.  Now it records the complete location of the
diagnostic instead of just the line number.

lint: warn about for wrong type cast in argument to ctype.h functions

The argument to most of the functions from <ctype.h> "shall either be
representable as an 'unsigned char' or shall equal the value of the
macro EOF".

When confronted with the infamous warning 'array subscript has type
char', there are enough programmers who don't know the background of
that warning and thus fix it in a wrong way.  Neither GCC nor Clang
explain its warning to target these programmers.

Both GCC and Clang warn about 'array subscript has type char', but they
ignore the other requirements of the <ctype.h> functions, even though
these are in the C standard library.

lint: add test for treating _Bool as non-scalar type

This strict mode is not yet implemented.  The plan is to use it for
usr.bin/make, to get rid of the many possible variants of defining the
Boolean type in make.h.  These variants did find some bugs, but not
reliably so.  Using static analysis seems more promising for this.

In an early stage of developing this test, lint1 crashed in the enum
definition in line 213, where the node for the '?:' had been NULL.  This
can happen in other situations as well, such as with syntax errors, but
these should be rare, as lint is usually only run if the compiler has
accepted the source code.  Still, there should not be any assertion
failures while running lint1.

lint: allow tests to specify additional flags

Several of the tests only need to add the -p flag.  Mentioning the
(current) default flags in each of these tests is redundant.  Therefore,
allow them to specify "lint1-extra-flags: -p" instead of the current
"lint1-flags: -g -S -w -p".

lint: fix integration test

The body of an ATF test must never return 1 but instead report failure
via atf_fail.  Otherwise the following error message appears:

    Failed: Test case body returned a non-ok exit code, but this is
    not allowed

The test program t_integration intentionally bypasses the official ATF
API for performance reasons.  But even then, it should stick to the API
as close as possible.

lint: demonstrate that -t mode is practically unusable

Since main1.c from 2014-04-18, running lint in -t mode produces strange
warnings in lines 1 to 3 of no file at all.

This is caused by the builtins that are parsed in main().  These
builtins are incompatible with traditional mode because they use long
double, which had not been known at that time.

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.

lint1: remove redundancy from test definitions

Whether a test is supposed to produce lint warnings is determined by the
corresponding .exp file.  There is no need to encode this information
redundantly in the test driver.

lint1: enable test cvt_constant

This test had never been enabled.  In t_integration.sh 1.3 from
2014-04-17 it was supposed to be enabled, but due to a line continuation
backslash, the words "test_case check_valid" ended up as the description
of the previous test, cvt_in_ternary.

While here, add the expected test output for d_struct_init_nested to
FILES.
