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);

There was a segfault probably due to taglib module changes.

It avoids useless es creation every time the current active es is destroyed.
