Stefano Sabatini 5085b46496 lavc: change type of AVFrame.channels field from int64_t to int

av_frame_*_channels() accessors return and set an int, so this should not
implicate ABI breaks.

Stefano Sabatini 271f411267 lavf/matroskaenc: avoid assert failure in case of cuepoints with duplicated PTS 
Avoid to write more than one cuepoint per track and PTS in
mkv_write_cues(). This avoids a later assertion failure on "(bytes >=
needed_bytes)" in put_ebml_num() called from end_ebml_master(), in case
there are several cuepoints per track with the same PTS.

This may happen with files containing packets with duplicated PTS in the
same track.
