Like all other panels.

Removes old complicated data model for codecs list, and replaces
it by a new and cleaner implementation. And there is no need to
hold dozens of input item references...

Uses NSWindowController to load the information panel. Get rid of
the singleton. VLCMain will now hold one instance, which is aimed
to display information about the currently playing media.

This reverts commit 6e1c08a2.
There are no leaks. All pointers must be NULL in the involved case.

This reverts commit 83d45830.
This was useless and not portable.

This reverts commit 6c5c07b9.
This made no sense. Picture dimensions cannot be zero or less (besides
the buffer is not used by the denoise function even then).

This reverts commit 3a22750e.
This made no sense; the predicate is always true.

This reverts commit 7661da70.
This does not fix the overflow as claimed.

This reverts commit e6ef1ae0.
This made no sense.

Adds helper method createItemsFromExternalPasteboard: returning
an array of file items from the pasteboard.
performDragOperation: in VLCCoreInteraction is the now only place
where we try to add the dropped file as a subtitle.

Logs are not recorded in background, so do not retain old logs
to avoid confusion.

Those rtf files were awful to read, and rather unhandy. Switch to
plain txt which should make debugging more easy.

Manipulate the data source on the main thread to fix some unprotected
accesses to the array.

Increase the maximum number of lines, for a more complete log.
