Move logging of current segment and stream. The previous place gave
confusing information.

After the adaptive bandwidth changes seeking could end up in a segment
that is not available. Each segment is downloaded once and after switching
to higher or lower bandwidth segments downloaded for previous bandwidths
will not be deleted or downloaded. The later is to be fixed.

Start playback with the lowest bandwidth stream.

NextSegment() assumed that the download thread its hls_stream_t was leading.
However this was too simplistic.

NextSegment() seeks the segment in *any* of the hls_stream_t, assuming that
each segment will be downloaded only once.

Test script for traffic shaping with tc (iproute).

Download the next segment from a playback standpoint.

Cleanup NextSegment().

The bandwidth calculation needed corrections and is less agressive in
switching to higher bandwidths.

(It was broken by a8e4b30b)

Move the definition to qt4.hpp and add a comment

If you want to use #description, you need to set up the appropriate
struct on pass it down as a variable

This also fixes error handling: if the thread cannot be created, we do
fail cleanly.

This allows using it at another time than destroying the object

...and less prone to deadlocks. This restarts until all keys are NULL,
in case cleaning up reset one key back to a non-NULL value.
There is still a slight difference with POSIX still. POSIX will restarts
only after all destructors have been invoked, not after the first one.

In practice, this bug was hidden by another bug in the thread variables
implementation: the destruction callback is never invoked.

This reverts commit eea468e6.

When the media is played, the formats represent decoder output, and the ids are not preserved (video ES can be replaced by audio ES)

This reverts commit 708a15ff.

Default skin becomes slightly transparent when moved.
(deactivated by default, needs to be set up in preferences)

Several redraw were no longer needed
(tested successfully on Ubuntu/metacity and WinNT)

On Win32, switching back and forth between layered Window and not layered
 window (case where only one of the two alpha parameters is < 255) was removed
because display was not satisfactory. (transition a bit weird)

This tiny patch enables opening of VideoCD/AudioCD/DVD discs with VLC in KDE when inserted, which was broken before.

The default skins now benefits from relative positioning:
   - main window centered
   - playlist window centered with a 5% offset
   - fullscreen controller centered at the bottom
     of the screen with a 3% margin from the border
   - other ancillary windows all centered

So far in skins2, all x, y, width and height were given in pixels, and
no reference to the screen resolution could be made.

This patch implements the following :
- all x, y, width, height can be given in pixels or in % of their container.
  For windows, the container is the screen. For widgets, it can be the
  layout or a panel.
- Five new tags eases up positioning
  - position : relative position given as "Center", "West", "NorthWest", ...
  - x/y-margin : margins to take into account (in px or %) wrt the borders.
  - x/y-offset : additional offset to apply (in px or %).
- the image control can now accept a width and a height parameters.
