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.

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.

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.

On LZMA_DATA_ERROR from lzma_index_buffer_decode(), *i = NULL was
already done but this adds a test for that case too.
(cherry picked from commit 575b11b0d2)
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.
(cherry picked from commit 7f865577a6)
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.

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.
(cherry picked from commit 4ffc60f323)
The API docs clearly say that if error_pos isn't NULL then *error
is always set on any error. However, it wasn't touched if str == NULL
or filters == NULL or unsupported flags were specified.

The array could become empty and then the initializer would be
simply {} which is allowed only in GNU-C and C23.

It is logical why it cannot know for sure that the value has
to be at most 4 if it is less than 16.
The x86 filter is based on a very old LZMA SDK version. Newer
ones have quite a different implementation for the same filter.
Thanks to Sam James.

On macOS, we get:
```
signals.c: In function 'signals_init':
signals.c:76:17: error: conversion to 'sigset_t' {aka 'unsigned int'} from 'int' may change the sign of the result [-Werror=sign-conversion]
76 | sigaddset(&hooked_signals, sigs[i]);
| ^~~~~~~~~
signals.c:81:17: error: conversion to 'sigset_t' {aka 'unsigned int'} from 'int' may change the sign of the result [-Werror=sign-conversion]
81 | sigaddset(&hooked_signals, message_progress_sigs[i]);
| ^~~~~~~~~
signals.c:86:9: error: conversion to 'sigset_t' {aka 'unsigned int'} from 'int' may change the sign of the result [-Werror=sign-conversion]
86 | sigaddset(&hooked_signals, SIGTSTP);
| ^~~~~~~~~
```
We use `int` for `hooked_signals` but we can't just cast to whatever
`sigset_t` is because `sigset_t` is an opaque type. It's an unsigned int
on macOS. On macOS, `sigaddset` is implemented as a macro.
Just suppress -Wsign-conversion for `signals_init` for macOS given
there's no real nice way of fixing this.
(cherry picked from commit 863f13d282)
A few lines were reordered, a few ARRAY_SIZE were changed to sizeof,
and a few uint32_t were changed to size_t. No real functional changes
were intended.
