When an item gets sub-items, we have to run our own random-picking among
the new items.

Fix two text controls overlapping by 1 pixel in length.
Though it's no real problem, that avoids unnecessary refresh for zilch.
(one control is the position that keeps being updated)

You need a recent enough libdvdnav. It is related to #4021.

It closes #4021 at the core level. The access_demux/demux need to set
input_title_t::i_length to actually change something.

It closes #3999.

Fixed colorthres/erase/extract/gaussianblur/gradient/motionblur/motiondetect/noise/psychedelic/sharpen filters.

input and output picture pitches may not be equal (corruptions or segfaults).

They are not yet really functionnal, the vout will throw the extra frames.

In the current lua vlm implementation, messages can have value xor
children but not both. But the "show media" command gives media a
value : ( %d broadcast - %d vod ) and children (if any). (cf
src/input/vlmshell.c:1502)

This is untested for the VLC module

selected items may not be erased (e.g ready-only items). Compute the new
lastSelected only if no more selection exists.

This fixes the extra selection popping up when one tries to
erase the media library for instance.
