bigben: this fixes that last little problem you had with the 'fullscreen button'

Break out meta-info gathering.
Various fixes and cleanups, but more work is still needed.
Some conceptual work on how things *should* work may be in order.

* configuration.c: don't crash on NULL values

* It enabled even when no vout is present
* Still a little issue with the fullscreen hotkey

* Lowered the opengl prioriy on OSX to speed up selection proces, while the thing is not working.

* modules/codec/toolame.c: lowered the priority of the toolame encoder and added the mp2/mp2a fourcc.

  - bug fixes in the decoder and encoder.
  - the decoder now returns YUVP subpictures.

Duration info is now set when playing entire CD so slider works again. 

More work is needed for playing single tracks, adding CD-Text info,
getting reference counts right.

* newer version of liveMedia

* forgot this file in the vlc_b64_encode patch

* Added the application/x-videolan-vlc and appllication/videolan-vlc mimetype to the OSX app
* NEWS: spelling error and remove the 'this version is not yet released' line. Before I forget :)

* evc/libvlc.vcp.in: small fix.

  - don't call waveOutUnprepareHeader() in the callback as the doc says it isn't advised.
  - use aout_ChannelReorder() for channels re-ordering.
  - a few bug fixes.

* Better Pragma header test. Apparently Pragma is a non required header in HTTP/1.1 This check should be more strict though perhaps not perfect.

  souls without Altivec. The new drawing was considerable slower to them.

- use existing default route when configuring crossbars, allowing users to configure video properties from a third party tools (eg, Video Tuner)

- invoked crossbar properties pages after graph has been created, changing video input should now work properly

* m3u.c: We now support http links to mms sources that don't send the Pragma line, but use a custom Referer file.

  These WiMP streams always have Pragma in the HTTP response, so we use
  this to identify them now.
