needed for DELTACAST, otherwise manpage generation fails with:

The file name has changed and --enable-deltacast was used just if the
download succeeded (which didn't).
Fixes the commit 98d4969b (2024-05-24) that disabled deltacast, because
the archive was not downloaded due to wrong name.
The documentation in header for
NDIlib_video_frame_v2_t.line_stride_in_bytes says that if set to 0,
default value (size of pixel * bpp) will be used.
However, this doesn't seem to work for P216 and PA16 in Windows. It does
in Linux, also 8-bit formats do not require that. However in Windows,
it causes "No data received.".
see also GH-148
Allow the MOD_NAME to be a variable (like (constexpr const char *)). Using
non-standard extension, the standard one would be __VA_OPT__. Although
it is supported with MSVC 2019/2022, it requires the compiler flag
/Zc:preprocessor.
This version doesn't require that so use it for now. The MSVC is used to
compile the CUDA code and AJA wrapper so not to complicate the things now.
This syntax is supported for both GNU and MSVC:

2. https://gcc.gnu.org/onlinedocs/cpp/Variadic-Macros.html

incorrectly braced
Actually not obvious until 2f450060 (2024-09-24) in master because the
chroma x1.5 was used but clamped, which has somehow hidden that.
the build fails after switch to macos-13 on manual page generation:
```

```
Please note that the corresponding error in master (from which was this
commit cherry-picked) was the following, which seems to be the same issue:
```

which tries to run bin/uv with --fullhelp.
(this fails only if run within the script data/make_man.sh, not when run directly)
macOS 12 is no longer supported and as Homebrew has a policy, that it
compiles packages from sources on unsupported macOSes, it is needed to
switch to newer macOS to keep reasonable build times.
pkg.m4 macro from pkgconf since 2.3.0 aborts by default if PKG_CONFIG
is not found, which check implicitly for pkg-config. Thus set
ACTION-IF-NOT-FOUND to allow fallback check for pkgconf.
fixes:
```
uv -t testcard:codec=RGB:size=1921x1080 -d sdl
```
Doesn't crash but errors are printed on console and data at the end
(perhaps something like a line) is not written.
Workaround to current MSVC error with CUDA 11.8:
```
C:\Program Files\Microsoft Visual
Studio\2022\Community\VC\Tools\MSVC\14.41.34120\include\yvals_core.h(888):
error: static assertion failed with "error STL1002: Unexpected compiler
version, expected CUDA 12.4 or newer."
```
CUDA 11.8 is used for compatibility with CC 3.5 (Kepler) devices. The
support for those will however end in 5 days [1] so we may swich to CUDA
12.x later.

ilibpipewire-0.3.so.0 was added to excludelist causing the distcheck fail,
see [1]
We do not need to exclude the lib, because we already handle the preload
in data/scripts/Linux-AppImage/AppRun:282 (the case is similar as for
libjack.so.0 as also mentioned in the related AppImage issue).

insteda to rtsp_state::rtsp_error_occurred, the error was printed to
some place of stack (the address of `s` variable on stack plus offset
of that attribute).
\+ added magic value to ensure
The printout includes pointer, which was at the time of writting supposed
to be 32, in which case the line length was:
2 /* 0x */ + 8 /* ptr */ + 1 /* : */ + 3 * 16 /* " XX" */ + 16 /* char repr */ + 5 /* additiona separators */ + 1 /* NL */ = 81
(separators - 2 betweeh group of hexa and char repre, 3 between hexa and char represenatation)
With 64 bit pinters, it can be at most 89 bytes. To keep the old length,
removed one space between every pair of hexadecimal byte representation -
it is still good legible, compatibile with xxd, still keeping the 80
long line..
Fixed correctly the problem that was incorrectly attempted by the
previous commit revert. should_exit doesn't need to be checked with the
main while loop because it is done by the inner one.
Together with the previous revert commit fixes CID 464437.
In addition to incorrect change to unsigned, also parenthesis around
(height - 1) were missing.
