not handled and delete_segments flag of hls_flags is broken now. This
patch fix this. The root cause of the bug was that HLSSegment struct
only stores the final filename part, but not the final directory path.
Most of the cases, final path info is unneded, It only necessary when
you want to delete old segments (e.g in case of live streaming).
Without variant streams it was unnecessary to store the final directory
path, because all segment were stored into the same directory. But
introducing %v in directory names either require to store the final
directory path into HLSSegment or associate segments with their variant
streams to be able deleting them later. I have choosen the second
solution and introduced a variant index data member into the segment
struct.

avformat/movenc: use correct iTunes copyright atom

Support for writing copyright metadata was added in commit bed4fc54c9
for 3GP, MOV and iTunes metadata. 3GP and MOV cases are formally
specified. However, iTunes format does not have specification, and
it seems to have been assumed that it would use the same atom as
MOV (both being Apple formats).

However, Apple uses 'cprt' atom for iTunes metadata (do note that
the iTunes 'cprt' encoding is generic iTunes ItemList atom, not
the 3GP 'cprt' encoding. These are also inside different parent
atoms).

Most references trying to document iTunes atoms mention only
the 'cprt' tag. See:
 - http://atomicparsley.sourceforge.net/mpeg-4files.html
 - http://mutagen.readthedocs.io/en/latest/api/mp4.html

Same applies to other software supporting this tag. Most of them
encode and decode only the 'cprt' atom.

ffmpeg mov demuxer supports both atoms in this context. There are
few pieces of other software that support similarly both 'cprt' and
the incorrect '\251cpy' atom in this context. I believe they do it in
order to read the ffmpeg encoded incorrect copyright atom.

In light of the above this changes the copyright atom to 'cprt' as
it seems to be supported univerally and is the correct atom to use.
