933dec0e29 file: Add an option for following a file that is being written 
Using this requires setting the rw_timeout option to make it
terminate, alternatively using the interrupt callback (if used via
the API).

ccea588f83 avio: Add an option 'rw_timeout' 
If set non-zero, this limits duration of the retry_transfer_wrapper()
loop, thus affecting ffurl_read*(), ffurl_write(). As soon as
one single byte is successfully received/transmitted, the timer
restarts.

This has further changes by Michael Niedermayer and Martin Storsjö.

05f66706d1 lavc: introduce a new decoding/encoding API with decoupled input/output 
Until now, the decoding API was restricted to outputting 0 or 1 frames
per input packet. It also enforces a somewhat rigid dataflow in general.

This new API seeks to relax these restrictions by decoupling input and
output. Instead of doing a single call on each decode step, which may
consume the packet and may produce output, the new API requires the user
to send input first, and then ask for output.

For now, there are no codecs supporting this API. The API can work with
codecs using the old API, and most code added here is to make them
interoperate. The reverse is not possible, although for audio it might.

0c6a70873f intrax8: Move error resilience out of intrax8 
The intrax8 decoding process does not imply any kind of error
resilience, and the only call present is more related to how mpegvideo
works rather than anything else.

Therefore have the parent decoders carry out er when actually needed.
