macosx: re-implemented the slower/faster menu items as a logarithmic slider similar to the Qt interface

This should fix buffer underflows in most cases.

Also move some stuff from vlc_config.h to vlc_aout*.h

Forward all available codec data to libavcodec

Closes: #4254

moved some elements around and renamed them within the 'Capture' tab

it's no longer called an 'iSight input', etc.

The user is not going to see the banner, and this tends to clutter
error logs (X server, cron jobs...) - not only on MacOS.

<vlc_es.h> includes <vlc_fourcc.h> already

reduce indentation level
concatenate a few lines
add a mention to #4005 in a comment
make a table static const
change style: ( bla ) -> (bla)

argument is a string ("on" or "off") not a bool

it automatically detects inserted disks and their type, so type selector by the user is no longer needed, which allows a much cleaner GUI

I don't want this plugin selected by default, only "file".

This changes filename from "latest" to explicit versioned name.
As official site doesn't provide old tarballs, we use
http://code.google.com/p/live555sourcecontrol/downloads instead.

Note: when updating contrib to new version, need to get checksum from
official site, not from there! Just in case...

Uses half hsv's value between background and foreground
(instead of mid palette color which is only revealant for drawing over
buttons colors)
