Lasse Collin 3334c71d3d xzdec: Support Landlock ABI version 4
This was added to xz in 02e3505991
but I forgot to do the same in xzdec.

The Landlock sandbox in xzdec could be stricter as now it's
active only for the last file being decompressed. In xz,
read-only sandbox is used for multi-file case. On the other hand,
xz doesn't go to the strictest mode when processing the last file
when more than one file was specified; xzdec does.

Lasse Collin 278563ef8f liblzma: Fix incorrect function type error from sanitizer
Clang 17 with -fsanitize=address,undefined:

    src/liblzma/common/filter_common.c:366:8: runtime error:
        call to function encoder_find through pointer to incorrect
        function type 'const lzma_filter_coder *(*)(unsigned long)'
    src/liblzma/common/filter_encoder.c:187: note:
        encoder_find defined here

Use a wrapper function to get the correct type neatly.
This reduces the number of casts needed too.

This issue could be a problem with control flow integrity (CFI)
methods that check the function type on indirect function calls.

Lasse Collin 77c8f60547 xz: Avoid arithmetic on a null pointer
It's undefined behavior. The result wasn't ever used as it occurred
in the last iteration of a loop.

Clang 17 with -fsanitize=address,undefined:

    $ src/xz/xz --block-list=123
    src/xz/args.c:164:12: runtime error: applying non-zero offset 1
        to null pointer

Lasse Collin 64503cc2b7 CMake: Support building liblzma API docs using Doxygen
This is disabled by default to match the default in Autotools.
Use -DUSE_DOXYGEN=ON to enable Doxygen usage.

This uses the update-doxygen script, thus this is under if(UNIX)
although Doxygen itself can run on Windows too.

Lasse Collin bdba39a575 Doxygen: Don't strip JavaScript anymore
The stripping method worked well with Doxygen 1.8 and 1.9 but
it doesn't work with Doxygen 1.10 anymore. Since we won't ship
pre-generated liblzma API docs anymore, the extra bloat and
extra license info of the JavaScript files won't affect the
upstream source package anymore.

Lasse Collin dc684bf76e Build: Omit PDF man pages from the package
pdf-local rule was added to create the PDFs still with "make pdf".
The install rules are missing but that likely doesn't matter at all.

Lasse Collin aaff75c348 CMake: Keep the build working if the "tests" directory is missing
This moves the tests section as is from CMakeLists.txt into
tests/tests.cmake. CMakeLists.txt now includes tests/tests.cmake
if the latter file exists.

Now it's possible to delete the whole "tests" directory and
building with CMake will still work normally, just without
the tests. This way the tests are readily available for those
who want them, and those who won't run the tests anyway have
a straightforward way to ensure that nothing from the "tests"
directory can affect the build process.

Lasse Collin a5f2aa5618 Tests: Remove x86 and SPARC BCJ tests
These are very old but the exact test file isn't easy to reproduce
as it was compiled from a short C program (bcj_test.c) long ago.
These tests weren't very good anyway, just a little better than nothing.

Lasse Collin 7f865577a6 Tests: test_index: Make it clear that my_alloc() has no integer overflows
liblzma guarantees that the product of the allocation size arguments
will fit in size_t.

Putting the pre-increment in the if-statement was clearly wrong
although in practice it didn't matter here as the function is
called only a couple of times.

Lasse Collin 71eed2520e liblzma: index_decoder: Fix missing initializations on LZMA_PROG_ERROR
If the arguments to lzma_index_decoder() or lzma_index_buffer_decode()
were such that LZMA_PROG_ERROR was returned, the lzma_index **i
argument wasn't touched even though the API docs say that *i = NULL
is done if an error occurs. This obviously won't be done even now
if i == NULL but otherwise it is best to do it due to the wording
in the API docs.

In practice this matters very little: The problem can occur only
if the functions are called with invalid arguments, that is,
the calling application must already have a bug.

Lasse Collin 4ffc60f323 tuklib_integer: Rename bswapXX to byteswapXX
The __builtin_bswapXX from GCC and Clang are preferred when
they are available. This can allow compilers to emit the x86 MOVBE
instruction instead of doing a load + byteswap as two instructions
(which would happen if the byteswapping is done in inline asm).

bswap16, bswap32, and bswap64 exist in system headers on *BSDs
and Darwin. #defining bswap16 on NetBSD results in a warning about
macro redefinition. It's safest to avoid this namespace conflict
completely.

No OS supported by tuklib_integer.h uses byteswapXX names and
a web search doesn't immediately find any obvious danger of
namespace conflicts. So let's try these still-pretty-short names
for the macros.

Thanks to Sam James for pointing out the compiler warning on
NetBSD 10.0.

or filters == NULL or unsupported flags were specified.
