[bug] Various methods have File related bugs impacting old DocumentFile use like rename

[Xavron]

Somewhat dated but if a certain upcoming pull request gets added then this easily becomes an option again.

Example:

https://github.com/ppareit/swiftp/blob/267ea09ad89a491d7be7a1dd170f07d45aa05dc6/app/src/main/java/be/ppareit/swiftp/utils/FileUtil.java#L176C1-L178C22

    private static boolean rename(File source, File target) {
        source.renameTo(target);
        return false;
    }

So, on Android 8, that is actually successful but returns false and then DocumentFile code runs to try again which can cause issues.

There's other methods that get into other possible issues like that in similar type methods. Should correct that as possibly more. I didn't directly look into others but had noticed various oddities happening.

Newer scoped storage code, if the pull requests are added, avoid this as I moved them above.

Can be closed if old DocumentFile code is to be left alone and only using new code instead for fixes.
