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.

Its replacement is still not ready.

This will allow us to avoid copying the packets in many cases.

This breaks ABI.

This allows us to get rid of them on the next major bump. All of the
above are functionally irrelevant, and most of them are unused, except
the vp3 one, which is used wrongly in the bfin arch optimizations.

The decoder also supports a12v, but removes the transparency layer
since no samples with actual transparency are available for testing.

Snow is a toy codec with no real-world use and horrible code.
