Part of MSC2140

Convert status codes to strings if there is a string status code. Fixes a build error when we mix 4xx and 403 in the same definition. We also have to correct stringified numbers to pass the build.

Damir Jelić a96a2f3fce Fix the action of a room key request cancellation.
The spec states that the action of a room key request cancellation
should be "cancel_request" but every known implementation uses
"request_cancellation" instead.

This patch fixes the spec to reflect the implementations.

Luca Becker d43111cdd2
Incorporated @turt2live suggestions.
Used **Note** to describe notes around the authorisation rules. Otherwise restored the original state for the consequences from the auth rules.
Moved the clarification regarding default power levels up above the auth rules. Removed third sentence. And followed @turt2live's example, but opted for "for users in that room" because the default user power level is applied to all users.

Luca Becker 094005dca1
Incorporated @turt2live suggestions.
Added missing added and removed to the rule, because these keys are not required for m.room.power_levels. Also moved the note down to the Note section.

Clarification regarding authorisation rules
The rules for m.room.power_levels power were somewhat unclear regarding the behaviour towards the always present keys, such as kick and ban. Additionally, it is now also clarified that in the users and events dictionary also added and removed keys are taken into consideration.

Less confusing wording on Application Service's Legacy Routes (#2160)
https://matrix.org/docs/spec/application_service/r0.1.1#legacy-routes

The "becomes" wording made it a little bit confusing for which was the new route and which was the old.

Jimmy Cuadra 5df86dabe0 Clarify the purpose of reference hashes.
The server-server specification describes a "reference hash" of an event
and how to calculate it, but is otherwise not mentioned anywhere else in
the document. This change adds a sentence to explain that they are used
for event identifiers in later room versions, which are described in
other documents.

J. Ryan Stinnett 4c65660b96 Clarify `.m.rule.room_one_to_one` push rule
This clarifies the `.m.rule.room_one_to_one` push rule by adding a condition on
event type. Some parts of the spec already had this info, while others were
missing it. Synapse has had this behaviour since the push rule appeared.

Fixes https://github.com/matrix-org/matrix-doc/issues/1527
Fixes https://github.com/matrix-org/matrix-doc/issues/1827

Note: In order to fix the "state events have the following fields: [no words]" bug (1827) we need to resolve references on common event types. When doing this we ultimately end up with more fields than may be required to explain the section, however this commit alters the section descriptions to just say "these fields" instead of "these additional fields".

This is also preferable over trying to get the inheritance reversed in the common event types, as the `/sync` endpoint has a high amount of reliance on partial events definitions.

No intentional divergences from the proposal are included in this changeset. There are a few additions which are used in practice although not defined in the proposal, such as who is responsible for aesthetics, sending notices, and other misc rules.
