For boop.mp3, this commit adds both ID3v1 and ID3v2 tags.  For boop.ogg,
we use Vorbis metadata.

In the case of boop.mp3, this also adds a cover image. Interestingly, it
didn't seem to affect the size of boop.mp3 much, despite being ~8k.
boop.ogg seemed to be much more affected and so no cover image was added
to that version.

[hash] is not documented.

We have changed how we store reblogs in the redis for bigint IDs. This process is done by 1) scan all entries in users feed, and 2) re-store reblogs by 3 write commands.

However, this operation is really slow for large instances. e.g. 1hrs on friends.nico (w/ 50k users). So I have tried below tweaks.

* It checked non-reblogs by `entry[0] == entry[1]`, but this condition won't work because `entry[0]` is String while `entry[1]` is Float. Changing `entry[0].to_i == entry[1]` seems work.
  -> about 4-20x faster (feed with less reblogs will be faster)
* Write operations can be batched by pipeline
  -> about 6x faster
* Wrap operation by Lua script and execute by EVALSHA command. This really reduces packets between Ruby and Redis.
  -> about 3x faster

I've taken Lua script way, though doing other optimizations may be enough.

Fix #5356

Specifically, this fixes status length calculation to be same as JS side.

BTW, since this pattern used in not only preview card fetching, we
should extract it (with twitter-regex?) and write tests I think.

* Clean up reblog-tracking sets from FeedManager

Builds on #5419, with a few minor optimizations and cleanup of sets
after they are no longer needed.

* Update tests, fix multiply-reblogged case

Previously, we would have lost the fact that a given status was
reblogged if the displayed reblog of it was removed, now we don't.

Also added tests to make sure FeedManager#trim cleans up our reblog
tracking keys, fixed up FeedCleanupScheduler to use the right loop,
and fixed the test for it.
