mp3: Decrease max sync seek length between frames to 4k
...
This might break mp3s with large id3v2 chunks embedded into the stream but
i think that is rare and probably means it is a dump of a mp3 radio stream etc.
An alternative approach is to also look for id3v2 etc between frames but then the mp3
root value probably should be an array of mix of things instead of a struct, or rename
header/footer to metadata?

tar: Don't assume there is a end marker
...
GNU tar docs says:
At the end of the archive file there are two 512-byte blocks filled with binary zeros as an
end-of-file marker. A reasonable system should write such end-of-file marker at the end of
an archive, but must not assume that such a block exists when reading an archive.
In particular GNU tar always issues a warning if it does not encounter it.
Also clean up API usage a bit
