v4l2: Factorize code, fix the video controls init, add Dennis Lou's contributions to the v4l2 module in THANKS.

macosx: if an input item includes a NowPlaying meta item, display it in our controller window instead some bogus MRL parsing stuff nobody can understand

misc/events.c: Fix event sending, by properly supporting event_manager edition (event_detach) while executing a callback (vlc_event_send). This is done through a recursive lock.

macosx: added an option to disable the 'Recent Items' list as requested by multiple forum users (closes #1340)

it.

You can not change a playlist_item_t to be a node, when you previously registered events on it, using input_item_t sub items adding event, because the pointer will be destroyed.
If you want to use nodes anyway, you have to explicitely create them.
Note: we were lucky that xspf did work so far, because we were EXCLUSIVELY using invalid pointers, except for the 1st item being added to each playlist_item_t (it did happen before the conversion obviously).

macosx: don't allow the user to open the preferences window multiple times (leading to orphan pref windows which can't be controlled)

audio_filter/converter/dtstospdif.c: Fix odd frame sized DTS conversion to SPDIF. Patch by Julien Robert <jul at mac.com>. (Reported to fix most of the current DTS issues).

control/hierarchical_node_media_list_view.c: Implement a view that only show the node of the media list, hierarchically.
