- by default, fullscreen is performed on the same monitor as the one
  where the video is currently being played back.
- support for --qt-fullscreen-screennumber if the user wishes to force
  fullscreen on a given monitor.

This fixes trac #4712. Tested on Linux. Tests needed for Windows.

The audio input drops expired packets before they hit the mixer. Since
we only support a single input per mixer, the mixer check is mostly
redumdant.

macosx: fixed disappearing repeat button images introduced in [8f79caa3e4b56c73c719bfa7c444cccbf203aa19]

Closes #4886

Main reason is that tt has the nicer subtitles support
Broken configurations (looking at you S3 and Matrox) will be able to use
the DirectDraw module.

Unsupported versions:
- Win9x (this is already the case)
- Win XP SP0, SP1
- Win 2000 (all editions)
- Windows 2003 SP0

Supported versions:
- Windows XP SP2, SP3
- Windows 2003 SP1
- Windows Vista, 7 and 2008

Audio volume should now work on !HAVE_FPU. This is untested though.

Both are present in recent nVidia cards. The latter is about the
Aug. 2010 revision of the DxVA2 WMV specification

Now the mixer can focus on applying to volume. Dummy mixers for
S/PDIF and linear are now merged.

Rather than automatically expanding folders when hoving over them, use this
information (folder expanded or not) to either insert the dropped item as its
next sibling in the parent folder or as its first child in this folder respectively.

This patch includes the following :
  - fix item misplacement (items were only appended instead of being inserted)
  - fix slider scrolling that could not adapt to the real size of the playlist
  - enhance drag&drop by allowing users to finely insert item being dropped
    into either the playlist or the media library.
  - optimise refresh (only rebuild playtree in case of visible item)
  - remove keeping a reference to a playlist_item_t* (since it is not
    refcounted, a lookup from the playlist with proper lock mechanism
    is needed)
  - remove the m_deleted flag (corner cases were never dealt with) and
    replace it with a notification prior to deletion
  - implement operator++ to simplify iterating visible items (cosmetics)

A deeper redesign/simplification and support for the new sql playlist would be a good thing though.

Pass drap&drop coordinates over to visual controls.
This feature will be used to allow users to finely insert items in the
playtree control instead of just appending them at the end.

Hand-crafted code in plugin descriptor is not allowed. And the code was
unsurprisingly buggy.
This reverts commit 1c2a95b8.
