[pvr] bump add-ons (fix version of addon.gui)
players: move more things into info structures for audio/video
dvdplayer: don't constantly hammer demuxer to get stream count

Note this could cause regressions in files where streams show
up during playback, but i think the demuxer signals such
situations now.
FIX: [droid] do not package non-standard joystick keymap
VSync: Drop OML Swap Method
VSync: Prefer Mesa Swaps to SGI Swaps
X11: use GLX_EXT_swap_control if available
VSync: Also drop SGI Interval
fixed: Typo in configure.in
load replaygain tags on mp4 style files
load tags when opening file so they are available when we try to read replaygain

provide a fallback file type to tagloader based on content

pass content type to DVDplayer for types that support tags, in order to set a fallback filetype
