This became a problem because #foundation-office:matrix.org has a
malformed create event with its `predecessor` set to a string instead of
a map.
The solution to this is, unfortunately, to do more shotgun parsing to
extract only the desired fields rather than trying to parse the entire
content every time. To prevent this kind of problem from happening
again, `RoomCreateEventContent` must only be used for creating new PDUs,
existing PDUs must be shotgun-parsed.
If all join requests to resident servers fail or if the joining server
is the only resident server (i.e. the room is local-only), we would
previously send a 500 error, even if the more correct response would be
M_UNAUTHORIZED (e.g. if the user tries to join an invite-only room).
To fix this, we now return the error generated by attempting the join
locally, which correctly informs the client about why their request
failed.
Fixes a set of bugs introduced by 00b77144c1,
where we replaced explicit `RoomVersionId` matches with `version < V11`
comparisons. The `Ord` impl on `RoomVersionId` does not work like that,
and is in fact a lexicographic string comparison[1]. The most visible
effect of these bugs is that incoming redaction events would sometimes
be ignored.
Instead of reverting to the explicit matches, which were quite verbose,
I implemented a `RoomVersion` struct that has flags for each property
that we care about. This is similar to the approach used by ruma[2] and
synapse[3].

For HTTP/1 requests, an inbound Request's URI contains only the path and
query parameters, since there's no way to synthesize the authority part.
This is exactly what we need for the X-Matrix "uri" field.
HTTP/2 requests however can contain the :authority pseudo-header, which
is used to populate the Request's URI. Using a URL that includes an
authority breaks the signature check.
Largely inspired by conduit MR !631
(https://gitlab.com/famedly/conduit/-/merge_requests/631).

The previous code used `server_name` as a fallback but in reality there
is no real relationship between `server_name` and the location clients
are supposed to make requests to.
Additionally, the `insecure` option is gone, because we now allow users
to control the entire URL, so they're free to choose the scheme.
This way users can have a simpler time configuring this stuff and we can
worry about the spec compliance parts and specifying the same thing over
and over parts.
Instead of working with v1 types and converting them to v2 as required,
do it the other way around. Allows us to remove a very broad
#[allow(deprecated)].
The spec defines that the media endpoints should return 504 when a file
is not-yet-uploaded, which has been interpreted to include when a file
was deleted. Modifies the /media/v3/download/ and /media/r0/thumbnail
endpoints.
Some duplicated-ish code from src/database/key_value/rooms/timeline.rs
about handling errors from `pdus_since`/`pdus_until`, it seems like the
error message was actually directly copy-pasted from there because it
referred to the wrong function lol
