avformat/utils: Stream specifier enhancement
Currently when specifying the program id you can only decide to select all stream of the specified program (e.g. p:103 will select all streams of program 103) or narrow the selection to a specific stream sub index (e.g. p:145:1 will select 2nd stream of program 145.) But you can not specify like all audio streams of program 145 or 3rd video stream of program 311. In some case, mainly working with multiprogram mpeg-ts containers as input, this feature would be handy. This patch makes it possible to narrow the stream selection among streams of the specified program by stream type and optionally its index. Handled types: a, v, s, d. Examples: p:601:a will select all audio streams of program 601, p:603:a:1 will select 2nd audio streams of program 603, p:604:v:0 will select first video stream of program 604.
