QCoreApplication: document the app's bindir is in libraryPaths()
The QCoreApplicationPrivate::appendApplicationPathToLibraryPaths()
function has been there since at least Qt 4.5.1, so the documentation
for appendLibraryPaths() hasn't matched behavior for a minimum of 13
years. The documentation for libraryPaths() has mentioned this fact,
though.
Searching the application's bin dir is normal on Windows, as many
application packages are a flat install with the .exe and all .dlls in
one dir. I find it questionable to do so on Unix, though: any and all
applications expecting to be installed by a Linux distribution would not
install plugins to /usr/bin, whereas on macOS bundles have their own
organization anyway.
But I'm not prepared to change the behavior without more justification.
I can think only of broken configurations (such what is described in
QTBUG-97950 where a combination of bad decisions led to scanning all of
/usr/bin) and running an executable that is stored in a world-writable
directory.
Task-number: QTBUG-97950
Pick-to: 6.2
