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

...and it is probably no use considering vout thread already has the
informations.

This reverts gullible commit 54b43fae. vout_Control() cannot be called
from another thread. Full point.

It was broken after being privatized.

input: send inputEvent when length if input changes

This one should fix #2435

It fixes a logical bug as the input and output format could be different.
(Not plugin that does that yet).
