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.

On LZMA_DATA_ERROR from lzma_index_buffer_decode(), *i = NULL was
already done but this adds a test for that case too.

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.

Lasse Collin 6aa2a6deeb liblzma: Silence a warning from Coverity static analysis
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.

Sam James 863f13d282 xz: signals: suppress -Wsign-conversion on macOS
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.

Sam James 73f629e321 ci: rename ci_build.sh -> ci_build.bash
We discussed the name and it's less cognitive load to just call it '.bash'

We need this for when we're passing sanitizer flags or -gdwarf-4 for Clang
with Valgrind. Just always start with -O2 if CFLAGS isn't set in the
environment and append what was passed on the command line.

Sam James 6c095a98fb ci: test Valgrind
Using `--trace-children=yes` has a trade-off here, as it makes
`test_scripts.sh` pretty slow when calling various non-xz utilities.

But I also feel like it's not useless to have Valgrind used there and it's
not easy to exclude Valgrind just for that one test...

I did consider using AX_VALGRIND_CHECK [0][1] but I couldn't get it working
immediately with some conditionally-built tests and I wondered if it was
worth spending time on at least while we're debating xz's future build
system situation.
