This reverts commit 60dbf2ef.

This is not needed anymore, Ticket 1694 has been fixed differently

This prevents various values from becoming stuck at NAN and
output to become silent
If someone knows a cleaner solution, thats welcome!

Fixes Ticket2335

Add AVBuffer-based reference counting API to it.

This field is private and should not be present in a public struct. It
is only used in DXVA with mpegvideo-based decoders currently.

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

This breaks ABI.

These could be used for reference counting, or for keeping track of
decoding progress in references in multithreaded decoders.

Support is provided by gcc/msvc/suncc intrinsics, with a fallback using
pthread mutexes.

When parsing the Xing/Info tag, don't set the bit rate if it's an Info tag.

When parsing the stream, don't override the bit rate if it's already set,
otherwise calculate the mean bit rate from parsed frames. This way, the bit
rate will be set correctly both for CBR and VBR streams.

The IIR filter numerically diverges in such cases, this could easily be
fixed but would make the filter slower on some platforms

This breaks the dependency of mpegvideo on error_resilience allowing
compilation of components that depend on the former w/o the latter.
