In particular, add support for t, pos, n, r parameters, and add an eval
mode option.
Also, partially reword option documentation.

This is a variant of showwaves. It is implemented as a different filter
so that the user is not allowed to use meaningless options which belong
to showwaves (such as rate).

Incidentally `-y` also collides with avconv global options.
Update x11grab to match and document the option.

The macro hell sometimes make it difficult to trace the source of
an error, so it is easier to analyze the preprocessed output.
This patch makes this automatical by specifying DBG=1 on the
command line: a file ffmpeg/dir/file.asm gets preprocessed to
builddir/dir/file.dbg.asm, which is then compiled.

This is necessary, because avcodec_decode_video2 can change
width, height and/or pixel format of the AVCodecContext. Since
video_dst_data and video_dst_linesize are not updated by calling
av_image_alloc again, av_image_copy[_plane] asserts, because the
destination buffer is too small.
In this case, creating a useable rawvideo is not possible anyway, since
it has fixed width/height/pix_fmt.

This adds an option to set the service type in mpegts as defined in ETSI 300 468.
I added what I believe are the most useful service types as pre defined values,
the others can be sent by using their hexdecimal form directly (e.g. -mpegts_service_type digital_radio, -mpegts_service_type 0x07).
I've been using this patch in order to pipe internet radio stream (originally as HLS/m3u8) from ffmpeg to tvheadend,
when the service type set right tvheadend recognize the mpegts stream as a radio channel.
The patch in its original form was written by linuxstb from freenode's hts channel which allowed me pushing it upstream.
This close issue 4118.
