- Fix local charset detection that broke (From|To)Locale

Found a simpler way to send an empty picture to the client. It fixes also memleaks introduced in 12196.

Send an empty subpicture to remove the OSD menu on the client application when "menu off" commands is given on the rc interface.

Bug reported by Thomas Knauer

It's already set to C globally because there are a bunch of things that
assume US-style float numbers formatting (config file, RTSP VoD server
to name a few) -- see SetLanguage() in libvlc.

If you want to get a float from the user, you can look for the comma
and replace it with a dot before parsing. However keep in mind that the
stream output parser already uses the comma to separate options; that's
yet another reason to use the dot in any case.

Also, I don't know if some remote locales use neither dot nor comma as
their decimal point.

   not been set to VLC_FALSE yet, the program number is not specified,
   and we're reading a PMT.
