qt4: fix embedding on unix
Qt: use QX11Info on Qt5 when present
macosx: video effects: increase crop stepper max value
macosx: video effects: add brightness-threshold to the profiles string

This is done in a backward-compatible manner: Once an existing profile is saved,
the new format is used.

Opening the new format with an old VLC version will work, too, but you will
lose changes from the new format.

refs #11643
macosx: add input changed event and reset shown crop values for new input
macosx: use input changed event to update bookmarks dialog

Search range for the new devices array was wrong, which led to nonworking
detection of removed devices, up to strange deadlocks when quitting VLC.
auhal: rework locking and avoid potential deadlock

hopefully closes #11675
image: remove dead code
image: remove constant parameter
