My opinion is that the search path feature is at the wrong level of 
abstraction. It's also a potential security issue, since filename handling 
might not catch the opening of files outside the specified user parameters. It 
makes the determination of whether a given file path is absolute or not 
ambiguous.

Those problems are shared by the file engines. Which we've fortunately got rid 
of for Qt 5.

In my opinion, the *correct* way of searching for a file is 
QStandardPaths::locate. If you need to determine whether the file should be 
opened or not, the API can return you an absolute file name, which you can 
manipulate.

This level of feature should be present on a VFS layer, above QFile and QDir.

So I'd like us to decide first: either we deprecate the search path 
functionality completely, or we accept them and use them. If we accept them 
for use, then I'm ok with adding the QStandardPaths there. Collisions with 
what users may have added are not important.
