Allocate avformat context and set its I/O context before using it
This is the correct way to it (and is documented in avformat.h)

On older OpenBSD releases you especially should not have been
using /dev/random, nowdays due to changes all the device nodes

to not special case OpenBSD in vlc_rand_init().

We want to use the new ones in our code

- Use AVIOContext instead of ByteIOContext
- Use avformat_open_input instead of av_open_input_stream
- Use avio_alloc_context instead of init_put_byte, allocate context on the heap
- Use AVIOContext.seekable

print avformat_open_input errors

avformat_open_input is the most recent and is documented as available since
libavformat 53.2.0 (other changes happened in 52.105)
avformat_open_input was introduced in 52.94 in FFmpeg

print avformat_find_stream_info errors

Pass its error output to msg_Err with %m

They were only used to hold one opaque pointer
