prefer "SAR" over "PAR" in av_dump_format()

Browse Source 
"SAR" (Sample Aspect Ratio) is globally preferred over "PAR" (Pixel
Aspect Ratio), although the two terms share the same semantics.

For example the corresponding AVStream field is called
sample_aspect_ratio, and libavfilter has a filter named setsar.

Therefore prefer the term "SAR" over "PAR" in the
libavformat/utils.c:dump_stream_format() and avcodec_string() output
for avoiding confusion.
