dcpomatic/test, branch v2.18.3

Fix invalid return values from fade() causing various odd effects (#2932).

2025-01-10T01:05:41Z

Add rfc_2822_date().

2025-01-09T19:56:26Z

Bump libdcp for raw_convert changes.

2025-01-05T11:58:13Z

raw_convert is gone, so here we use fmt::{to_string,format} instead. Other raw_converts now use fast_float.

Give ownership of info files to ReelWriters (#2912).

2024-12-26T16:20:25Z

The motivation here is to stop a pattern where we create a file, close it, and then re-open it (many times) as I think there are problems on Windows when a virus scanner sees the new file, opens it for checking, and then we can't re-open it. This also makes things a fair bit simpler, as a lock is removed and we don't try to differentiate read/write cases by opening the file in different ways; it's now always writeable.

Rename guess_crop -> guess_crop_by_brightness.

Bump asdcplib for Windows UTF-8 filename fix.

2024-12-26T15:46:02Z

Setup path encoding for Windows in tests.

2024-12-26T15:46:02Z

Then we can create boost::filesystem::paths from UTF-8 literals without everything going west.

Fix hang when encoding with GPU enabled but not working.

2024-12-18T09:51:44Z

Assert if we're about to set up 0 encoding threads.

2024-12-09T00:40:48Z

Use all cores when encoding in tests.

2024-12-09T00:40:48Z

I think this also avoids the possibility of setting the master encoding thread count to 0 by mistake on machines that don't have many cores.
