81cec35dbf Custom emoji (#4988)
* Custom emoji

- In OStatus: `<link rel="emoji" name="coolcat" href="http://..." />`
- In ActivityPub: `{ type: "Emoji", name: ":coolcat:", href: "http://..." }`
- In REST API: Status object includes `emojis` array (`shortcode`, `url`)
- Domain blocks with reject media stop emojis
- Emoji file up to 50KB
- Web UI handles custom emojis
- Static pages render custom emojis as `<img />` tags

Side effects:

- Undo #4500 optimization, as I needed to modify it to restore
  shortcode handling in emojify()
- Formatter#plaintext should now make sure stripped out line-breaks
  and paragraphs are replaced with newlines

* Fix emoji at the start not being converted

c8969dca35 Minor Chinese check & jsx addition (#4973)
* zh-*: transition from "like" back to "fav"

This commit reverts the translation for the yellow-star "fav" button
back to "fav" in Chinese. Some ambuiguity between "like" and "fav" is
deliberately used in zh-TW/HK by using the existing phrase "最爱"
(favorite (adj.), lit. love-most) instead of "收藏" (favourite (v.),
"collect") in some instances.

Fixes #3511.

* zh-*: apply suggestions for PR #4557

* zh-cn: de-monetize ya account

In Chinese two separate characters, 账 and 帐, can be used to spell the
word for account (账/帐户). However, the one with a 贝 on the left is
evolved from the latter specifically for monetary purposes. Since
people usually can't figure out which one to use, it might be a good
idea to use the original not-so-money one.

* zh-*: complete jsx translation

c30e6433de Fix AP serialization error when thread is missing (#4970)
`Status#reply?` may returns true even if the thread is missing.
e.g. the replied status was deleted or couldn't be fetched.

Then it raises NoMethodError on various AP json serialization.

This issue won't happen on Atom serialization because it checks thread
existence using `StreamEntry#threaded?` instead.

f29918e707 [WiP] Whenever a remote keypair changes, unfollow them and re-subscribe to … (#4907)
* Whenever a remote keypair changes, unfollow them and re-subscribe to them

In Mastodon (it could be different for other OStatus or AP-enabled software),
a keypair change is indicative of whole user (or instance) data loss. In this
situation, the “new” user might be different, and almost certainly has an empty
followers list. In this case, Mastodon instances will disagree on follower
lists, leading to unreliable delivery and “shadow followers”, that is users
believed by a remote instance to be followers, without the affected user
knowing.

Drawbacks of this change are:
1. If an user legitimately changes public key for some reason without losing
   data (not possible in Mastodon at the moment), they will have their remote
   followers unsubscribed/re-subscribed needlessly.
2. Depending of the number of remote followers, this may generate quite some
   traffic.
3. If the user change is an attempt at usurpation, the remote followers will
   unknowingly follow the usurper. Note that this is *not* a change of
   behavior, Mastodon already behaves like that, although delivery might be
   unreliable, and the usurper would not have known the former user's
   followers.

* Rename ResubscribeWorker to RefollowWorker

* Process followers in batches

0a6b098668 Fix count numbers from ActivityPub not being saved (#4899)
They are marked as read-only by Rails, but we know what we are doing,
so we are un-marking them as such.

The mastodon:maintenance:update_counter_caches task is not really
supposed to be run anymore (it was a one-time thing during an upgrade)
however, just in case, I have modified it to not touch ActivityPub
accounts.

Also, no point writing to logger from these rake tasks, since they
are not to be run from cron. Better to give stdout feedback.

1ae5d49a71 Refresh timeline after toot while the timeline is disconnected (#4858)
To reflect status posting immediately, we've inserted the status into timelines directly. However, status insertion changes "latest status", and it means next timeline refresh only fetches statuses since the inserted status. This behavior is very bad for disconnected timeline and mobile views.

After this patch, it refreshes timeline for disconnected timelines, instead of direct insertion.

a12572e074 Handle stream_entry URL correctly in ActivityPub (#4854)
In before, the method uses stream_entry id as status id, so replied status was wrongly selected.

This PR uses StatusFinder which was introduced with `Api::Web::EmbedsController`.
