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.

Those are not part of the API and ABI compatibility "promise"

This patch does the following
   - do not reset m_firstPosition when not needed
   - fix corner case when playlist is flat (prone to crash)
     The node with a single leaf being deleted should become the
     next leaf. But, actually just forcing the rtree.begin()
     in any case is simpler and no problem here.

Deleting an item can either be initiated by the user or coming from the core.
In one case, a m_deleted flag was added and notify occured before
deletion to avoid invalidated iterators.
This patch ensures that the other case is processed likewise.

This path simplifies code a bit, makes index consistent throughout the code
(spanned from 0 to n-1), and remove a += maxitems that seems wrong

- check validity before using iterators
- don't use iterator anymore once the item is erased
