Should save a bunch of kilobytes of code.

Objects have been renamed (vlc.MediaPlayer/vlc.Media) to match the current API.

This implies the removal of playlist support (single-file playing only, through set_mrl/get_mrl methods). Position parameters for _pause, _resume and _stop method have also been removed.

Note that the only aim of this array seems to be counting the non-node items

Remove VLC_META_ENGINE_*
Don't use VLC_META_INFO_CAT
Avoid using input_Item{Add,Get}Info
Remove disabled code in cdda
Remove "meta fetcher":
    There was only 1 module (not) implementing it (musicbrainz)
    Reduces complexity in playlist core
Use a more consistent naming
Factorize QT4 sorting and column display code
Remove unused members

This breaks module aliasing.

This reverts commit 16afc893.

Add coordinates settings for mosaic pictures. (This kind of duplicates the --mosaic-offsets setting which I'm thinking about removing.)

The "unknown, always 0" field looks very much like it is the not used 32

httpd: Fix vlc_object_wait() usage. It's needed to check if we were not already killed before calling vlc_object_wait(). Thanks to William King for spotting the deadlock.

Fix error in undef zvbi private define ZVBI_PIXFMT_RGBA32 and fix compiler warnings for unused arguments.

Like for qt4 or skins2
