43b7068070 parseutils: make av_parse_time() check for failure. 
Until now, av_parse_time() would accept "1:00" as "1"
and silently ignore ":00".

This patch also includes a few cosmetic changes.

70d54392f5 lowres2 support. 
The new lowres support is limited to decoders where lowres decoding
is possible in high quality.
I was not able to measure any speed difference, but if one is found
the 2-3 lines that might affect speed can be made compile time conditional
