Add support for linking XMPP URIs in toots (#12709)

* Fix wrong grouping in Twitter valid_url regex

* Add support for xmpp URIs

Fixes #9776

The difficult part is autolinking, because Twitter-text's extractor does
some pretty ad-hoc stuff to find things that “look like” URLs, and XMPP
URIs do not really match the assumptions of that lib, so it doesn't sound
wise to try to shoehorn it into the existing regex.

This is why I used a specific regex (very close, although slightly more
permissive than the RFC), and a specific scan function (a simplified version
of the generalized one from Twitter).

* Remove leading “xmpp:” from auto-linked text

Suppress backtrace when delivering toots (#12798)

This is to suppress irrelevant backtrace from errors raised when
delivering toots to remote servers. The errors are usually out of
control by the local server and backtraces don't provide much
information.

This is similar to https://github.com/tootsuite/mastodon/pull/5174
and shortens backtraces like below:

Use heading actions and placeholders in settings (#12801)

This commit:

- Refactors centered text blocks currently used for placeholders
  for empty tables and puts styles for it in separate class -
  .centered-text, simply aliasing text-align: center. Which is
  furtherly used in this commit.

- Improves applications settings page to use heading actions, moving
  "New application" button there, and displaying placeholder "You
  have no applications" in place of empty table.

- Improves custom emoji settings page to use heading action
  for "Upload" button, making it more easily accessible without
  need to scroll through all of the emojis.

- Improves email domain blocks settings page, moving "Add new" to the
  heading actions and using placeholder "No e-mail domains currently
  blacklisted" instead of showing empty table.

Add CircleCI task to test migrations (#12815)

Rename page_heading_actions variable (#12799)

Current name - page_heading_actions is long and hard to remember,
this commit shortens it to just heading_actions, which is way more
easier to remember and write, it's logical too.

Add --remote-only option to emoji purge (#12810)

Allow blocking TLDs, and fix TLD blocks not being editable (#12805)

Fixes #12795

It was already possible to create domain blocks for TLDs, but those
weren't enforced, nor editable. This commit changes it so that they
are enforced and editable.

Little improvements to filters settings page (#12793)

When you have many filters, it may be hard for you to reach the button
to create yet another one. This commit moves creation button to the
heading, leaving the page just for the list.

On the other hand, when there are no filters, page looks kind of
strange with the empty table. So text stating obvious fact that user
has no filters was added in this commit too.

Summary: fix slowness due to layout thrashing when reloading a large … (#12661)

* Summary: fix slowness due to layout thrashing when reloading a large set of status updates

in order to limit the maximum size of a status in a list view (e.g. the home timeline), so as to avoid having to scroll all the way through an abnormally large status update (see https://github.com/tootsuite/mastodon/pull/8205), the following steps are taken:
•the element containing the status is rendered in the browser
•its height is calculated, to determine if it exceeds the maximum height threshold.
Unfortunately for performance, these steps are carried out in the componentDidMount(/Update) method, which also performs style modifications on the element.  The combination of  height request and style modification during javascript evaluation in the browser leads to layout-thrashing, where the elements are repeatedly re-laid-out (see https://developers.google.com/web/fundamentals/performance/rendering/avoid-large-complex-layouts-and-layout-thrashing & https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Performance_best_practices_for_Firefox_fe_engineers).
The solution implemented here is to memoize the collapsed state in Redux the first time the status is seen (e.g. when fetched as part of a small batch, to populate the home timeline) , so that on subsequent re-renders, the value can be queried, rather than recalculated.  This strategy is derived from https://github.com/tootsuite/mastodon/pull/4439 & https://github.com/tootsuite/mastodon/pull/4909, and should resolve https://github.com/tootsuite/mastodon/issues/12455.

Andrew Lin (https://github.com/onethreeseven) is thanked for his assistance in root cause analysis and solution brainstorming

* remove getSnapshotBeforeUpdate from status

* remove componentWillUnmount from status

* persist last-intersected status update and restore when ScrollableList is restored

e.g. when navigating from home-timeline to a status conversational  thread and <Back again

* cache currently-viewing status id to avoid calling redux with identical value

* refactor collapse toggle to pass explicit boolean

Fix old migrations failing because of strong_migrations update (#12692)

Fixes #12690

The `strong_migrations` update from ba2eac8824a85aa9541f8070ed7bcd22b9982cc8
introduced a check for `change_column_null` specific to Postgres. This rejects
old migrations.

This commit just wraps old migrations with `safety_assured` to bypass this
check. Alternatives would have been to:
- Disable that check entirely (a possibility added in that same
  `strong_migrations` version) for Mastodon, but it makes sense to write new
  migrations without such a strong lock.
- Rewrite the old migrations to do it in a way that do not require an exclusive
  lock. I thought fixing those old migrations for performance wasn't worth the
  pain. Also, if I understand correctly, the next version of
  `strong_migrations` is going to include a helper to do that. We could update
  those migrations at that point.

Fix sample SAML_ACS_URL, SAML_ISSUER (#12669)

Use eslint cache (#12668)

Update link to install docs (#12666)

Correct the Nanobox deploy hooks for order and context (#12663)

One hook was actually duplicated incorrectly; this has been fixed. Another hook was re-ordered for better results in actual use.

Use different strings on exports page (#12569)

Currently the page re-uses strings from other contexts which doesn't fit
very well - strings incorrectly lowercase-d and pluralized, when they
don't need to be, because it's a table.

This commit changes page to re-use accounts.posts_tab_heading for toots,
and admin.accounts for "Following" and "Follows". This all should look
more aesthetically pleasing.

Fix manual scrolling issue on Firefox/Windows (#12648)

Fixes #12607

`will-change: transform` apparently makes manual scrolling impossible on
Firefox/Windows. While this should probably be considered a Firefox bug,
`will-change: transform` seem like a very aggressive performance hint that
may possibly make the browser consume more resources than needed, especially
in multiple-column mode.

This was originally added to improve scrolling performances on mobile, but
I think this isn't necessary anymore, because of the two following reasons:
- `contain: paint` (which is implied by `contain: strict`, which we apply
  whenever the browser supports grids) should have similar effects
- in single-column mode, the scrolling container is the root element, which
  I believe is optimized in at least Chromium

Keep in mind that I have not been able to make in-depth benchmarks, and
especially not been able to try on mobile, so performances should probably
be investigated further…

fix multiple space (#12655)

[Security] Bump rack from 2.0.7 to 2.0.8 (#12654)

Fix unsafe column type change in migration (#12653)

Fix custom emoji category creation silently erroring out on duplicate category (#12647)

Instead, just re-use the existing category if any.

Fixes #12608

Remove unused translatable strings (#12643)

* Remove unused “salmon_url” string

* Remove more unused translatable strings

The following strings all used to be on the admin account page
but aren't used anymore: profile_url, outbox_url, followers_url, feed_url

Fix link crawler not specifying accepted content-type (#12646)

The link crawler expects HTML documents, so set the `Accept`
header accordingly.

Fixes #12618

Add signature to exported status (#12649)
