based on patch from Neal Symms <nsymms # redwar.us>
with minor cleanups

Change some message severities

  video by a fixed panel (format .uyvy). Specify panel files with
  --sout-switcher-files=toto.uyvy,tata.uyvy,titi.uyvy and the size of
  pictures with --sout-switcher-sizes=720x576,720x576,480x576.
  --sout-switcher-port=4242 opens up a UDP port. echo 1 | nc -u localhost 4242
  switches to panel #1 (0 is the live video, -1 disables all output).
  The audio is blanked out when a panel is active. --sout-switcher-command
  specifies the first command to run on start-up.
* modules/access/fake.c: Fake video input simulating a video at x fps.
  Use it to switch between fixed panels with the switcher when you have
  no video.

* modules/misc/freetype.c: better outlining algorithm + generate 16 colors (instead of 256) palettized YUV.

- String fixes
- Sort some large panels
- Change some advanced flags
- Fix & move audio-channel-mixer
- hide picture vout
- Remove saved-volume, replaced by a variable

There's still a segfault somewhere (occurs after many seeks but I can't reproduce it with a debugger)

- modules/access/http.c: do not choke when there's a space in a URL
  (should probably be done for some others)

- Sorted marq options
- A52 & DTS are audio decoders
- Moved freetype to subtitles/OSD

(last 2 suggested by Anil)

* upgraded libcdio to 0.7.2 (not that it makes much difference :) )
