  ismindex: handle time discontinuities and nonzero start time
Merged-by: Michael Niedermayer <michaelni@gmx.at>

This adds a new option -hls_flags single_file that creates one .ts file
for HLS and adds byteranges to the .m3u8 file, instead of creating one
.ts file for each segment.

This is helpful at least for storing large number of videos, as the
number of files per video is drastically reduced and copying and storing
those files takes less requests and inodes.

This is based on work by Nicolas Martyanoff, discussed on ffmpeg-devel
in July 2014. That patch seems abandoned by the author, and contained
unrelated changes. This patch tries to add the minimum amount of code to
support the byterange playlists.

The input file may not have consistent start times, stream durations and
chunk durations. This patch at least removes negative durations that
make chromecast unhappy, and correctly sets starting time on chunks so
that the split (or .ismf) outputs match the manifest.

Handles decoding of new VP9 profiles 1-3 with different color sampling
and bit-depths.

For high bitdepth (profiles 2 and 3) support, we currently need to link
with the highbitdepth branch of libvpx with --enable-experimental
and --enable-vp9-high config options on. But eventually this branch will
be merged into master, whereafter to enable high bitdepth
support you will need to link with libvpx with configure option
--enable-vp9-highbitdepth on.
