Merge remote-tracking branch 'qatar/master'

* qatar/master:
  avconv: extend -r to work on any input stream.
  doc/avconv: expand documentation for the -s option.
  avconv: don't print filters inserted by avconv in stream mappings.
  avconv: merge configuration code for complex and simple filters
  avconv: split configuring input filters out of configure_complex_filter

Conflicts:
	configure
	doc/ffmpeg.texi
	ffmpeg.c

+As an input option, this is a shortcut for the @option{video_size} private
+option, recognized by some demuxers for which the frame size is either not
+stored in the file or is configurable -- e.g. raw video or video grabbers.

+As an output option, this inserts the @code{scale} video filter to the
