To keep treatments unified, do similar special treatment for "images/*.jpg"?

Alternatively, appending the subdir name to docfiles does the trick. @josephwright Is this the expected behavior or a misused "feature"?

Another idea: if \input@path/\l_file_search_path_seq is respected by \pgfutil@IfFileExists and \pgfutil@InputIfFileExists (see #1259), then we can drop prefix plots/ in manual examples

\tikz \draw plot[mark=x,smooth] file {plots/pgfmanual-sine.table};

From conversation in latex3/l3build#331 and a casual check in l3build source, yes it is supported. I tend to use this currently undocumented feature in pgf's l3build configuration.

As this PR also promotes missing plot data file from warning to error, feature breaking change in l3build will be caught.

\usetikzpackage raises error for unknown package name. I'm now leaning towards (officially) promote "Plot data file not found" from warning to error.

As d1ada29 didn't pass the "Check commits" check, I reorganized commits and reworded CHANGELOG entries (perhaps overly), and force pushed again (sorry).
