Follow-up to #8766

Regression from #8942

* Downcase signed_headers string before building the signed string

The HTTP Signatures draft does not mandate the “headers” field to be downcased,
but mandates the header field names to be downcased in the signed string, which
means that prior to this patch, Mastodon could fail to process signatures from
some compliant clients. It also means that it would not actually check the
Digest of non-compliant clients that wouldn't use a lowercased Digest field
name.

Thankfully, I don't know of any such client.

* Revert "Remove dead code (#8919)"

This reverts commit a00ce8c92c.

* Restore time window checking, change it to 12 hours

By checking the Date header, we can prevent replaying old vulnerable
signatures. The focus is to prevent replaying old vulnerable requests
from software that has been fixed in the meantime, so a somewhat long
window should be fine and accounts for timezone misconfiguration.

* Escape users' URLs when formatting them

Fixes possible HTML injection

* Escape all string interpolations in Formatter class

Slightly improve performance by reducing class allocations
from repeated Formatter#encode calls

* Fix code style issues

* Set CSP rules in RoR's configuration

* Override CSP setting in the embed controller to allow frames

Regression from #8951

* Do not push DMs into the home feed

* Show DMs column after sending a DM, if DMs column is not already shown

Mention and emoji code may perform network calls, but does not need
to do that inside the database transaction. This may improve availability
of database connections when using pgBouncer in transaction mode.

Fix #8685

* cleanup pass

* undo mistakes

* fixed.

* revert

SignatureVerification#matches_time_window? is not called anywhere.

* Add conversations API

* Add web UI for conversations

* Add test for conversations API

* Add tests for ConversationAccount

* Improve web UI

* Rename ConversationAccount to AccountConversation

Configurable soft limit of 7,500, and above that, configurable
ratio of 1.1 * followers, controlled by:

- MAX_FOLLOWS_THRESHOLD
- MAX_FOLLOWS_RATIO

Fix #2311

Ruby's ** operator does not play well with non-Hash objects, which
the params slice is

* Fix HomeFeed#from_database not using paginate_by_id

* Revert "Fix some icon names changed by the Font Awesome 5. (#8796)"

This reverts commit 3f9ec3de82.

* Revert "Migrate to font-awesome 5.0. (#8799)"

This reverts commit 8bae14591b.

* Revert "Fix some icons names, unavailable in fontawesome5 (free license). (#8792)"

This reverts commit b9c727a945.

* Revert "Update the icon name changed by the Font Awesome 5. (#8776)"

* Revert "Add bot icon to bot avatars and migrate to newer version of Font Awesome (#8484)"

This reverts commit 4b794e134d.

* Changed list behaviour

I added the following line to the FeedManager (app/lib/feed_manager.rb) in the push_to_list function:

`return false if status.reply?`

Now all posts that are replies are filtered out, so that now only "genuine" posts are displayed in the list.

This is a first approach to solve issue #5916

* Update feed_manager.rb

As suggested by @Gargron

Fixes #8755

Show "read more" link on overly long in-stream statuses

- pencil => pencil-alt
- sliders => sliders-h
