Modules are created at initialization and destroyed at exit (after all
VLC threads are terminated) There is no need to count references.

This property is fundamentally per-plugin, not per-submodule.

This field is never used for submodules, and in fact there would be no
way to show it in the (current) UI.

This is the same as module_t.pp_shortcuts[0].

Use NULL rather than a static string as the default.
module_get_object() deals with this situation.

The module will never be proved. This applies to the "main" module
and the playlist demux (which only has submodules).

Zero-length strings are loaded as NULL. There are probably quite a few
other similar failure cases :( I have not investigated.

For example, x264's git is one.

This is not really needed. Cache corruption would be detected anyway.
But better safe than sorry.

We do not need them afterward.

This avoids seeking. This data was not useful.

 * Add the org.mpris.MediaPlayer2.Player.Seek method introspection data
 * Update the copyright headers

 * Use an int64 argument
 * Update the copyright headers

Else the check on i doesn't make sense
