This does not support hot plug and unplug of devices.

Also, it prevented selecting a device not in the choices list due to
checks in the variables subsystem. (At least with ALSA, not all valid
devices are included in the suggestions.)

Far too many bugs in this code path recently.

Using var_Set("device") is wrong: the "device" variable holds the
currently used output device (as set by the aout plugin), not the
intended output device (as requested through the user interface).

Also fix a memory leak.

If I understood correctly, drive letters are always ANSI

Weirdly, there is no GetProcAddressW, indeed

Since OutputDebugStringW is just a wrapper around OutputDebugStringA

This requires bleeding-edge libavcodec.

    - fix behavior of video-on-top by adapting to vout windows handling changes
    - set all windows to status level if one vout window has this level:
    This avoids that video effects panel, audio efffects panel etc. pp. are opened behind
    a vout window. Now they can be used as usual.

    Please note, that due to the type of these panels they do not remain visible
    when VLC gets inactive.

If we're using the new background renderer which just renders the
background under the text (instead of the entire subpicture block),
then don't call the legacy render as well.  This prevents a alpha-
transparent box from being shown when rendering EIA-608 captions
if the user has the Freetype background opacity set to a nonzero
value.
