The associated libvlc_MediaPlayerBuffering and libvlc_Buffering value could
probably be removed (not done as I do not know the maintainer opinion).

They will allow interfaces to display the current buffering status.

 The associated libvlc_MediaPlayerStopped and libvlc_Stopped value could
probably be removed (not done as I do not know the maintainer opinion).

The spu has to be detached from the vout object, otherwise the vout will
never be destroyed.

 It removes the need of INPUT_GET_BYTE_POSITION/INPUT_SET_BYTE_SIZE which where
not thread safe.

We do it more properly when creating a source anyway.

Cosmetic on the file too.

We were always picking the same values. This is pretty bad as it breaks
fast resynchronization (and is totally lame anyway).

This module make possible uses libvlc as output (not input as vmem) for
video stream rendering in aplication ... motivation to create this patch can
find at http://forum.videolan.org/viewtopic.php?f=32&t=53256

Usage is similar to vmem output module. We need next vlc_argv[] options:
   "--codec", "invmem",
   "--invmem-width", width,
   "--invmem-height", height,
   "--invmem-lock", clock,
   "--invmem-unlock", cunlock,
   "--invmem-data", cdata,
and calling libvlc_media_new with "fake://" access string:
   libvlc_media_new(libvlc, "fake://", &ex);

us_asprintf() has the same prototype as asprintf(), but doesn't use
the system locale.
