lavc: export the timestamps when decoding in AVFrame.pts

Browse Source 
Currently it's exported as AVFrame.pkt_pts, which is also the only use
for that field. The reason it is done like this is that lavc used to
export various codec-specific "timing" information in AVFrame.pts, which
is not done anymore.

Since it is confusing to the callers to have a separate field which is
used only for decoder timestamps and nothing else, deprecate pkt_pts and
use just AVFrame.pts everywhere.

API changes, most recent first:
2016-xx-xx - xxxxxxx - lavc 57.24.0 - avcodec.h
Decoders now export the frame timestamp as AVFrame.pts. It was
previously exported as AVFrame.pkt_pts, which is now deprecated.
2016-xx-xx - xxxxxxx - lavu 55.16.0 - hwcontext.h hwcontext_qsv.h
Add AV_HWDEVICE_TYPE_QSV and a new installed header with QSV-specific
hwcontext definitions.
