Fully discarded streams can't be selected for output or mapped or filtered.
Previously, a few packets from such streams, probably buffered for
stream probing, would get smuggled into output files.

Forced key frames generation functionality was assuming the first PTS
value as zero, but, when 'copyts' is enabled, the first PTS can be any
big number. This was eventually forcing all the frames as key frames.
To resolve this issue, update has been made to use first input pts as
reference pts.

potential NULL dereference.

For some strange reason "-t" option was only implemented
for input files while both "-t" and "-to" were available
for use for output files. This made extracting a range from
input file inconvenient.
This patch enables -to option for input so one can do
ffmpeg -ss 1:23:20 -to 1:27:22.3 -i myinput.mkv ...

Merges Libav commit b9129ec466.
