* Use grid layout for the landing page

* Fix column settings

Set the ratio explicitly

* Improve information board

- Add follow/unfollow/remote follow buttons
- Format the bio properly
- Always show username@domain, even for local accounts

* Fix prev/next links on public profile page

* Don't make pagination urls if no available statuses

* Fix empty check method

* Put left chevron before prev page link

* Add scope for pagination "starting at" a given id

* Status pagination try 2:

s/prev/older and s/next/newer
"older" on left, "newer" on right
Use new scope for "newer" link
Extract magic 20 page size to constant
Remove max_id from feed pagination as it's not respected

* Reinstate max_id for accounts atom stream

* normalize

* Ensure the app does not even start if OTP_SECRET is not set

* Remove PAPERCLIP_SECRET (it's not used by anything, actually)

Imports are for internal consumption and the url option isn't even
used correctly, so we can remove the hash stuff from them

UglifyJS2 is allowed to mangle function names, and function names can also
be duplicate if they are from different scopes. Therefore function names
are not reliable as identifiers.

Functions as keys for Map object is a cheaper and more reliable
alternative.

* Update Japanese translations.

* Add quotation marks.

A complemental change for precompute_feed_service_spec.rb also fixes its
random failure which is caused by the Snowlake randomization of the order
of an original status and its reblog.

* document pam email extraction

* remove superfluous newline

* Add focus param to media API, center thumbnails on focus point

* Add UI for setting a focal point

* Improve focal point icon on upload item

* Use focal point in upload preview

* Add focalPoint property to ActivityPub

* Don't show focal point button for non-image attachments

It was merge when it needed to be deep_merge. And added some tests

* Fix #201: Account archive download

* Export actor and private key in the archive

* Optimize BackupService

- Add conversation to cached associations of status, because
  somehow it was forgotten and is source of N+1 queries
- Explicitly call GC between batches of records being fetched
  (Model class allocations are the worst offender)
- Stream media files into the tar in 1MB chunks
  (Do not allocate media file (up to 8MB) as string into memory)
- Use #bytesize instead of #size to calculate file size for JSON
  (Fix FileOverflow error)
- Segment media into subfolders by status ID because apparently
  GIF-to-MP4 media are all named "media.mp4" for some reason

* Keep uniquely generated filename in Paperclip::GifTranscoder

* Ensure dumped files do not overwrite each other by maintaing directory partitions

* Give tar archives a good name

* Add scheduler to remove week-old backups

* Fix code style issue

* Fix avatar and header issues by using custom geometry detector

Revert a part of #6508. The file passed to dynamic styles method
was not actually a file, but an instance of Paperclip::Attachment,
which broke all styles by always returning {} from the method.

One problem with GIF avatars was that Paperclip::GeometryDetector
reported wrong dimensions for them, e.g. 120x120 GIF avatar would
for some reason be detected as 120x53. By writing our own geometry
parser, we can use FastImage, which also happens to be faster than
ImageMagick, to detect image dimensions, which are also correct.

Unfortunately, this PR does not implement skipping a `convert`
entirely if the dimensions are already correct, as I found no easy
way to write that behaviour into Paperclip without rewriting the
Paperclip::Thumbnail class.

* Only invoke convert if dimension or format needs to be changed

* Set Docker permissions during the build process

* Remove docker_entrypoint.sh and use COPY with chown

Also don't apply "-quality 80" option which is probably the reason
for slight color differences between original and remote image
(because it would apply it twice, once on original instance, and
again on the receiving instance)

- 4px rounded corners on media attachments
- Better colors/contrast for CW/media spoiler on public pages
- Fix vertical alignment of "Show more" button
- Fix layout jump when unhiding standalone media

* Added #link_header spec

* Added #call spec

* Delete spec of private methods

* Added call test case activitypub

* Cache relationships in API

* Fetch relationships for search results in UI

* Only save one account's maps in each cache item

The cache store is explicitly used by some specs, but they were not
isolated and therefore not reliable. This fixes the issue by clearing
the cache after each specs.
