As reported on forum, Powercam Pro returns 38 system IDs

Hypothesis: The bug stems from a thread concurrency problem. A PLModel::rebuild() happens
just between SD inserting items into the core playlist and Qt playlist receiving item-added callback.
Thus, the items referred to the callback are inserted twice into the Qt playlist.

Solution: check if item already inserted at callback processing.

This reverts commit 0adb9ceb.

The changes needed are not the same.

This makes the plugin stay at a reasonable size (120kB vs 1090kB stripped)
This might not be optimal though...

This reverts commit b8dc2568.
In the case of SDL, the actual resize is done in VOUT_DISPLAY_CHANGE_DISPLAY_SIZE
without any risk of infinite loop.

This is now working since the previous "--static" commit

Libcddb doesn't work as advertised, you need regex to make it work.
Regex is supposed to be in your libc, but isn't in mingw... Great...
So, add a regex target and patch libcddb to not build tests and examples
Also, don't use AC_FUNC_MALLOC and REALLOC when crosscompiling and change the .pc file

Then we don't need to process all root window property events.

This reverts commit bcfa778f.

Else we have troubles executing $FOO when FOO=prog --some-options
Should fix [5d6f80f2]

Only tested on a minimal win32 build. Please report configure/linking failure

Patch taken from upstream svn

The widget is hidden by default, no need to call hide in the
constructor.

The widget reparentable already has the layout.

The QPalette of the widget is already stored in QWidget, there is no
need to have an attribute for it.

should fix #3112 again ;) . Playlist still has issue to crash if current item is
destroyed, but thats different issue

This reverts commit edcc45df.

This causes segmentation faults and breaks SD categories.

Of xcb-utils, we only use xcb-keysms at the moment. xcb-keysyms is only
needed for the globalhotkeys and xcb_window plugins. If there is another
window provider plugin, we can do without them so long as the user does
not set --no-embedded-video.

Note: xcb-utils is still needed for the LibVLC embedded video as it
depends on xcb_window. We could  #ifdef the key press support in
xcb_window if this is an issue (I didn't bother).

Should fix #3112 and maybe make it littlebit cleaner (hopefully)

This seems to fix #3114 maybe some other tickets too
