* avformat: Avoid allocation for AVFormatInternalAndreas Rheinhardt2021-09-17
| | | | | | | | | | | | | Do this by allocating AVFormatContext together with the data that is currently in AVFormatInternal; or rather: Put AVFormatContext at the beginning of a new structure called FFFormatContext (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVFormatInternal altogether. The biggest simplifications occured in avformat_alloc_context(), where one can now simply call avformat_free_context() in case of errors.

* avcodec/bsf: Unref the packet when flushingAndreas Rheinhardt2021-09-14
