emotion: add libvlc module

Summary:
Everything is implemented except visualization, mouse events and some
EMOTION_EVENT. Video can output RGBA, YUY2, YV12 or I420.

About the video sink: this emotion module use libvlc callbacks:
libvlc_video_set_format_callbacks and libvlc_video_set_callbacks. It may be
temporary. Indeed, an other solution is to add an Evas module inside vlc. But
this vlc module would need to link with emotion in order to use
_emotion_frame_new and _emotion_frame_resize private functions. I didn't
succeed to output a frame without these private functions: see
https://github.com/tguillem/vlc/commit/15daff4d3fdcd3ca7b485c1f8fabb8c1e1c4138c

List of /* FIXME */:

 - Visualization not implemented since there is no API (for now) in libvlc.

 - Mouse events not implemented since there is no API (for now) in libvlc.

 - Some EMOTION_EVENT are not handled.

 - SIGSEGV in evas_gl_common_texture_nv12_update with
   EVAS_COLORSPACE_YCBCR420NV12601_PL colorspace.
