attempt to fix issues with segfault reported on list

Wave and ripple should now behave correctly for chromas where pixels can take more than 1 byte in a row (like RV32).

v4l2: Since the frame size and frame intervals ioctls are new in Linux 2.6.19, add some ifdef stuff to make sure that this still compiles on older kernels.

v4l2: Display supported frame interval (inverse frame rate) for chosen chroma and resolution in debug output.

widget-size, 1. try from me

Qt4 - Extended dialog, group audio things under an Audio Tab. put the audio and video tabs on the left.

Changes to the lua module's declaration: add luahttp alias and don't make it accept the luameta alias for all capabilities.

Re-enable EXTVLCOPT: parsing in m3u playlists. You'll need to append the --m3u-extvlcopt option to you command line if you want it.

* modules/access_output/shout.c: Implement automatic reconnection on server disconnect - closes #1167

Why don't we use an enum in that file ???

Inheritance rules...

MacOSX/Framework/VLC_app: Use the bindings a little bit more. Demo the search feature. Uses shoutcasttv by default to have some content by default.

MacOSX/Framework: No more rely on media_descriptor_(get/set)_user_data, now that we cache the media decriptor. (We may want to revert that back one day, but right now this doesn't work, and trigger some strange bugs here).

MacOSX/Framework/VLCMediaListAspect.m: Use a NSMutableArray to cache the media list view items. (for the same reason given in previous commit).

MacOSX/Framework/VLCMediaList.m: Cache the media list objects in a NSMutableArray. We do this because we want to use bindings. Cocoa bindings requires us to send willChangeValueForKey/didChangeValueForKey on the main thread. And that's one of the simpler way to do that without having locking problems.

heavy simplification, and fix(/remove) piles of error cases.
Server gets to choose the charset anyway.
