["Feature" request] Ignoring case of iwad filename for Linux users when loading custom wad?

[bslenul]

Hey!

For Linux users, would it be possible to completely ignore the case for the iwad filename when loading a custom wad?

For example, if I want to load SIGIL and have DOOM.WAD/DOOM.wad/Doom.wad/doom.WAD/etc., it wont load because its looking for doom.wad and nothing else.

I'd also like this.
But it's tricky because of the range of platforms needed to support and the fact that we can't just spam the disk reading for alternative casing.

The right way would be reading the directory and iterating over the list of files (something like this). But it would be slow if the user has a bazillion files, specially because of the recursive search. It'd be better if there was some globing support to only retrieve files with the right extensions and so. This is probably something that should be added to libretro-common, since I imagine it's useful for usecases in other cores too.

the only problem I see is that all of those files with different cases can exist at the same time and if that happens. which file should be opened?
