Fix #7893
Fix #7615

This replace calls of String#match? with rails Regex#match?
This follows the same idea used to keep Rails 5.2 compatible with Ruby
2.2.2 in https://github.com/rails/rails/pull/32973

Fix #7903

* Re-add follow recommendations API

    GET /api/v1/suggestions

Removed in 8efa081f21 due to Neo4J
dependency. The algorithm uses triadic closures, takes into account
suspensions, blocks, mutes, domain blocks, excludes locked and moved
accounts, and prefers more recently updated accounts.

* Track interactions with people you don't follow

Replying to, favouriting and reblogging someone you're not following
will make them show up in follow recommendations. The interactions
have different weights:

- Replying is 1
- Favouriting is 10 (decidedly positive interaction, but private)
- Reblogging is 20

Following them, muting or blocking will remove them from the list,
obviously.

* Remove triadic closures, ensure potential friendships are trimmed

* Make embeds cacheable by reverse proxy

* Make follow button on embeds open remote follow modal

Instead of web+mastodon://, also, turn the button blue, and add a
sign up prompt to the remote follow modal

`@signature_verification_failure_reason` is used in most places but`@signed_verification_failure_reason` appears in two places. Likely those errors are not returned.

If Mastodon accesses to the hidden service via transparent proxy, it's needed to avoid checking whether it's a private address, since `.onion` is resolved to a private address.
I was previously using the `HIDDEN_SERVICE_VIA_TRANSPARENT_PROXY` to provide that function. However, I realized that using `HIDDEN_SERVICE_VIA_TRANSPARENT_PROXY` is redundant, since this specification is always used with `ALLOW_ACCESS_TO_HIDDEN_SERVICE`. Therefore, I decided to integrate the setting of `HIDDEN_SERVICE_VIA_TRANSPARENT_PROXY` into` ALLOW_ACCESS_TO_HIDDEN_SERVICE`.

* Add keyword filtering

    GET|POST       /api/v1/filters
    GET|PUT|DELETE /api/v1/filters/:id

- Irreversible filters can drop toots from home or notifications
- Other filters can hide toots through the client app
- Filters use a phrase valid in particular contexts, expiration

* Make sure expired filters don't get applied client-side

* Add missing API methods

* Remove "regex filter" from column settings

* Add tests

* Add test for FeedManager

* Add CustomFilter test

* Add UI for managing filters

* Add streaming API event to allow syncing filters

* Fix tests

Merge upstream changes

While this isn't exactly *wrong*, files uploaded with a “.jpe” extension will
keep that extension, which will often cause them to be served with an
incorrect mimetype.
