* Rename i_playing to is_playing
* Handle case of p_md being NULL.

When the plugin fails to open the framebuffer, then the mmap might
not have been done yet. In this case a segmentation fault will occur
when memset is called on p_sys->p_video. (p_sys->p_video is either NULL,
or MMAP_FAILED.)

When set from the config file

I hope they will reduce the risk of error until the playlist API is rewritten.

 The previous code mixed up playlist_item_t->i_id and input_item_t->i_id and
 so this callback was unusable.

This reverts commit 394a9e2c.

This doesn't really fix the issues, so better to revert and rework it.

This doesn't solve the fact that ItemChanged_Type is called WAY too often... Fenrir, ILEoo, ideas?

Revert "Qt: deinline createStatusBar() and explicit statusBar creation." and Fix StatusBar - close #2523

This reverts commit f509b90d.

Qt: toolbar-profile, provide 4 profiles, one being close to 0.8.6 interface, the other one close to 0.9.0 and too smaller ones.

Default can be changed, please give ideas.

Close #2521
