The result of meta fetching is not cached (except the artwork), but this could be an envisionned goal for the media library.

Print a list of available alsa output devices in debug output if the user specified a non existing device. Simple example to get the listing: /vlc --aout alsa,none --alsa-audio-device bla -vvv file.mp3 --verbose-objects -all,+alsa

This is not needed anymore. Modules are not in the bank at all anymore

Don't try to handle other codings with it. As of today, IANA lists
compress, exi and pack200-gzip as other legal values.

Layouts and Controls are interrelated. Whatever the ones first deallocated, it leaves pointers referencing objects already destroyed. and potentially means memory leak.

This patch adds an unsetLayout() function to pair the setLayout() function and aimed at releasing resources.
Policy should now be that things allocated in constructor are released in destructor and things allocated in setLayout are released in unsetLayout.

Remove the old way of tracking change in vout size (no longer used)

In today's implementation, notifyLayout() for a control leads to a whole
 layout rebuilt. Therefore, this function must be called _only_ if needed.

- Never needed in onResize() since we are already in the process of rebuilding
the whole layout. Calling notifyLayout() means the job is done twice.
- Never needed in onPositionChange() for the same reason as onResize().
- Not needed for a checkbox since already called in setImage() two lines above.

intf-change for playlist is never updated

When reparenting, these values must be updated to avoid unnecessary resizing
if the move() method is called.

This skins demux is not of much use, but at least, it is now functioning.
(no more crash)

Fix #3232

Otherwise, the object files will conflict

PLD was only added to I420 -> YUYV this far.
