Use XCB abstraction to Xlib for communication to X11 server. The following
additional changes were needed:

- Split modules/video_output/xcb/xcb_vlc.c in 2
	xcb_vlc.h	 - SHM and PictureResourceAlloc/PictureResourceFree
	xcb_events_vlc.h - matches implementation of modules/video_output/xcb/events.c

The new Peek() function now allocates a block (p_sys->peeked) if the
required size (i_peek) is greater than the size of the playback
segment, and then do a copy of one (or several) segment's data block(s) in it.
In the end, p_sys->peeked might be the concatenation of several segment's data
blocks, but usually it will be NULL.

The decoder takes care of that.

Currently, this is used to trigger resampling in the audio "input"
(i.e. filters) as before.
