It's supposed to be called only from (de)muxers.

Manual replacements are done in this commit.

In many cases, the id is some constant made up number (e.g. 0 for video
and 1 for audio), which is then not used in the demuxer for anything.
Those ids are removed.

It's more readable and less prone to breakage.

This eliminates a warning about a set-but-unused variable.

Most of these variables are only used in av_dlog statements, some
are required but not used by other macros.

If an MP3 file contains the string NSVs, the NSV probe will confuse it for an
NSV file. Check for 0xBEEF after a Video/Audio chunk to achieve more accuracy.

In the name of consistency:
get_byte           -> avio_r8
get_<type>         -> avio_r<type>
get_buffer         -> avio_read

get_partial_buffer will be made private later

get_strz is left out becase I want to change it later to return
something useful.

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.

av_metadata_set() is going to be dropped at the next major bump.
