Export vlc_str2keycode()

This is needed for global hotkeys. In the best of worlds, I think the
global hotkey plugins would directly get the list of keycodes to grab
using a dedicated plugin type. This would avoid the need to replicate
hotkey configuration parsing. But it would need some more work.
