ffplay: remove unused variable "codec"

Fix warning:
ffplay.c: In function ‘video_thread’:
ffplay.c:1890:21: warning: unused variable ‘codec’ [-Wunused-variable]
ffplay: remove options skiploop, skipidct, skipframe

The corresponding codec options (skip_loop, skip_idct, skip_frame) can be
set in a more flexible way.

This technically causes a user interface break, but since the options
were not even documented and we just released a major version that should
not be a serious issue.

mpeg: Add passing DVD navigation packets (startcode 0x1bf) to caller to allow better playback handling of DVDs.

The two types of packets (PCI and DSI) are passed untouched but combined by the new codec ID AV_CODEC_ID_DVD_NAV.
 The first 980 bytes in the packet contain the PCI data. The next 1018 are the DSI data.
