Fix support for HTTP proxies (#11245)

* 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

Merge commit 'c07cca4727041ea5a5721acbc603d4bfb45a15a6' into glitch-soc/merge-upstream

Unlike upstream, kept the direct timeline endpoint, as it is still of use in
glitch-soc.

Only scroll to the compose form if it's not horizontally in the viewport (#11246)

editing long toots.

Fix HTTP requests to IPv6 hosts (#11240)
