* Disable incorrect check for hidden services in Socket

Hidden services can only be accessed with an HTTP proxy, in which
case the host seen by the Socket class will be the proxy, not the
target host.

Hidden services are already filtered in `Request#initialize`.

* Use our Socket class to connect to HTTP proxies

Avoid the timeout logic being bypassed

* Add support for IP addresses in Request::Socket

* Refactor a bit, no need to keep the DNS resolver around

* Remove Salmon and PubSubHubbub endpoints

* Add error when trying to follow OStatus accounts

* Fix new accounts not being created in ResolveAccountService

Avoids jumping the scroll around vertically when giving it focus and
editing long toots.

The instrumentation code was used for StatsD metrics collection
prior to the switch to the nsa gem and should have been removed
at that point as it no longer does anything at all

Use the smallest preset expires_in such that the new poll would
not expire before the old one.

In the typical case of a quick delete & redraft, this results in
using the same poll duration.

Fixes #10567

* Add request pool to improve delivery performance

Fix #7909

* Ensure connection is closed when exception interrupts execution

* Remove Timeout#timeout from socket connection

* Fix infinite retrial loop on HTTP::ConnectionError

* Add some tests

* Add more tests

* Reduce MAX_IDLE_TIME from 90 to 30 seconds, reap every 30 seconds

* Use a shared pool that returns preferred connection but re-purposes other ones when needed

* Fix wrong connection being returned on subsequent calls within the same thread

* Reduce mutex calls on flushes from 2 to 1 and add test for reaping

When editing a custom filter, select the shortest preset duration that
still covers the remaining time of that filter.

Fixes #9506

Resolve #11187

* Optimize makeGetStatus

Because `ImmutableList.filter` always returns a new object and `createSelector`
memoizes based on object identity, the selector returned by `makeGetStatus`
would *always* execute.

To avoid that, we wrap `getFilters` into a new memoizer that memoizes based on
deep equality, thus returning the same object as long as the filters haven't
changed, allowing the memoization of `makeGetStatus` to work.

Furthermore, we memoize the compiled regexs instead of recomputing them each
time the selector is called.

* Fix memoized result being cleared too often

* Make notifications use memoized getFiltersRegex

In some occasions, such as the browser or a browser extension auto-filling
the existing but disabled/hidden CW field, a CW can be set without the user
knowing.
