Provide means to hide configuration, libraries, copyright information, build info but retain input and progress info

[Iwan Gabovitch]

I use ffmpeg directly in the command line.

When debugging, the progress report information is very useful but the block of information about copyright, build, configuration and library version info is redundant and disturbs the formatting of the visible text in the terminal.

I always have trouble finding the output of a previous command when for example using ffmpeg in a shell script together with other commands.

-loglevel quiet hides all of the mentioned above. Including the desired progress information.

Please provide means of hiding copyright, build, configuration and library version information without hiding the progress information.

I am not sure if it is a good idea to support not showing the banner, but I sent a patch that adds a new option -show_banner (which defaults to 1).
