macosx: fixed volume slider appearance in black intf mode and disable the track slider when appropriate

removed remnants of the Dudiak interface, added PXSourceList by Alex Rozanski (BSD-new licensed) which will be used for the new implementation, added a to-be-replaced png for the window's topbar

macosx: remove 2 interface update timers (2 threads), 1 additional interface update thread and replaced everything by callbacks

macosx: moved preliminary vout to main window, removed most interface related parts from VLCMain, implemented theming for the main window

the former embedded window is no longer accessible

this also prepares a mainwindow object and includes some clean-up

minor functional changes only

The thread are already created with the right priority. If not, then
vlc_clone() should be fixed instead.
Also, the vlc_thread_set_priority() calls on the main interface thread
seem bogus, as the target thread is dedicated to monitor the libvlc
death and is not the main running thread.

closes #4721

No functional changes. Some more can't be replaced yet, as we still support 10.5

MacOS: fixes an issue with the recents item that doesn't list the opened media since changes made in b0620aea6b50d3062d1240e6d4a3945ca40b5e92.

pl_Hold() assumed the playlist was already created.
pl_Release() does not solve any problem. Playlist synchronization is
done with the playlist lock, while playlist deletion must anyway be done
after all interfaces, services and other threads are joined.

The previous fix made the fetcher and preparser persistent throughout
the lifetime of the playlist. So we don't need to protect the pointers
anymore. Also, they are internally thread-safe (with their own lock).

In general, we should avoid PL_LOCK'ing around stuff that the Datasource does,
and restrict it to the lines that directly deal with the core playlist.

This should fix #2810

Add a few more lockings around other playlist data as well. We really need to redo all this stuff.
