avconv: get rid of new* options.

They are confusing, irregular and redundant -- -map already contains all
the information.  Stream maps can now be parsed in opt_output_file().

Add a more user-friendly default behavior in case no maps are present.

Breaks -programid for now, but it never worked properly anyway. A better
solution will be written soon.

+@c man begin STREAM SELECTION
+
+By default av tries to pick the "best" stream of each type present in input
+files and add them to each output file. For video, this means the highest
+resolution, for audio the highest channel count. For subtitle it's simply the
+first subtitle stream.
+
+You can disable some of those defaults by using @code{-vn/-an/-sn} options. For
+full manual control, use the @code{-map} option, which disables the defaults just
+described.
