Revert revision 13903. It is implemented in a different way by checking if the option --dshow-chroma is set. If it is set then the chroma is forced, otherwise it is not. This should solve the regression of previous commit, by letting users specify the chroma type to use. To get the previous default behaviour specify IV420 as preferred chroma type either on the commandline or in the Capture Device advanced tab.

  No longer use the charset of the OS. OS X is UTF-8 for instance, but most subs are simply in Latin-1.
* In case we did BOM detection with stream_ReadLine, set subsdec-encoding to UTF-8 automatically.

Get input bitrate

Remove unconditionally enforcing of "preferred" media type upon the capture devices. Some devices don't handle this properly, which often results in a BSOD. By not setting a preferred media type the problem dissappears. Please check this with other type of devices for any regression.

(like double clicking on a file or disc) use the --one-instance option.

People used to running 10 instances of VLC at once should now be able
to do so. Normal people used to running other media players should now
get the behavior they expect (ie: not open 10 different VLCs when double
clicking on 10 mp3s)

(if only we had a cleaner UPnP stack)

* ctrl_checkbox.cpp: animated bitmaps are now supported in checkbox controls

 into the p_private attribute of the vlc_object(NNNN). Used by embedding
 applications.

several VLC instances at once should be able to disable this option in
the prefs.

Fix compilation

  - fix last bugs with SPDIF stream selection
  - code and debug cleanup
  - added more comments to clearify the code, so it is useful to others :D

* Set FD_RDAHEAD and FD_NOCACHE on when reading from files. improves reading from networkshares and VMEM usage.
