This race will always happen sooner or later in a multi-threaded
environment and it will over time lead to OOM.
This fix works by spinning, there are other ways by which this
can be fixed, like simply detecting the issue after it happened
and freeing the over-allocated memory or simply using a mutex.

Those are not usable from the avtools, so mentioning them in the
manpages just confuses the reader.

The total frame size is a combination of the 12 bits in the sequence
header and 2 more bits in the the sequence extension. While the
specification explicitly forbids the dimensions from the sequence header
from being 0 (thus ruling out multiples of 4096), such videos
apparrently exist in the wild so we should attempt to decode them.

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.

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.
