Due to file_list_free()'s behavior of free()ing userdata as if it was a
simple, contiguous structure xmb_node_t's fullpath member wasn't being
free()'d.
Each xmb_node_t instance used over 4KiB of memory even when it didn't
need to. In big list like MAME (30+ thousand entries) RetroArch would
consume over 100MiB (4096 bytes * 30000) just to hold all xmb_node_t
instances.
Fixes a regression where fading animations didn't render if you were far
into the previous list. This happened because "current" has an incorrect
value thanks to a menu_navigation_set_selection(0) call in
menu_cbs_left.c:162
Allow xmb menu driver transparency when "Pause when menu activated" is enabled (default setting).
This is also the default behaviour of the rgui driver and is helpful for users to preview
video/shader changes on the fly.
Issues fixed:
gfx/video_driver: enable menu transparency only when game is loaded (as a loaded core can display
black or corrupt image)
gfx/video_driver: don't clobber cached frame during driver reinit if game was loaded
(fixes missing menu background/paused foreground on full screen toggle)
menu/drivers/xmb: ensure transparency is applied when game is loaded and no shader pipeline active.
menu/menu_driver: explicitly apply transparency only for existing textures (i.e. wallpapers), to
avoid background of cores with no content yet loaded mixing with wallpaper.
