Add authenticated media (MSC3916) (#1858)
* C2S: Deprecate now-legacy endpoints * C2S: Fix MXC URI code block while we're here * C2S: Describe the authentication and deprecation requirements * C2S: Intro the upload/download endpoints differently * C2S: Literally copy/paste the `content-repo.yaml` spec * C2S: Drop `/upload` and `/create` because we aren't replacing them today * C2S: Fix notes while we're here * C2S: Update metadata for new endpoints * C2S: Add authentication to new endpoints * C2S: Drop `allow_remote` and `allow_redirect` on new endpoints * C2S: Append backwards compatibility notes * C2S: Decorate old media endpoints with pointers to the new ones The server-server spec might have a harder time linking to these, but that can be fixed with verbiage. * C2S: Annotate IdP icon spec with media auth implications * S2S: Modernize section text * S2S: Create content repository API This is largely a copy/paste of the new authed content repo API in the Client-Server API, though some keywords (like "client") have been changed. Paths and response formats have also been changed to support the federation-specific requirements. * C2S & S2S: Add plethora of changelogs * Reference RFC 1341 * Upgrade keywords in changed text * Mention caching * Cross-reference IdP icons * Update content/client-server-api/modules/content_repo.mdpull/1861/head

thumbnails typically use the content types `image/gif`, `image/png` (with APNG format),

`image/apng`, and `image/webp` instead of the common static `image/png` or `image/jpeg`
|

content types.
|

|

When `true`, the server SHOULD return an animated thumbnail if possible and supported.
|
||||
When `false`, the server MUST NOT return an animated thumbnail. For example, returning a
|

static `image/png` or `image/jpeg` thumbnail. When not provided, the server SHOULD NOT

return an animated thumbnail.

Servers SHOULD prefer to return `image/webp` thumbnails when supporting animation.
|

|

When `true` and the media cannot be animated, such as in the case of a JPEG or PDF, the

server should behave as though `animated` is `false`.

`Content-Disposition` headers as appropriate;

2. or a `Location` header to redirect the caller to where the media

can be retrieved. The URL at `Location` SHOULD have appropriate

`Content-Type` and `Content-Disposition` headers which describe

the media.
|
||||
|
||||
When `Location` is present, servers SHOULD NOT cache the URL.
|
||||
The remote server may have applied time limits on its validity.
|

If the caller requires an up-to-date URL, it SHOULD re-request
|

the media download.

Indicates preference for an animated thumbnail from the server, if possible. Animated

thumbnails typically use the content types `image/gif`, `image/png` (with APNG format),

`image/apng`, and `image/webp` instead of the common static `image/png` or `image/jpeg`
|
||||
content types.
|
||||
|
||||
When `true`, the server SHOULD return an animated thumbnail if possible and supported.
|
||||
When `false`, the server MUST NOT return an animated thumbnail. For example, returning a
|
||||
static `image/png` or `image/jpeg` thumbnail. When not provided, the server SHOULD NOT
|
||||
return an animated thumbnail.
|
||||
|
||||
Servers SHOULD prefer to return `image/webp` thumbnails when supporting animation.
|
||||
|
||||
When `true` and the media cannot be animated, such as in the case of a JPEG or PDF, the
|

server should behave as though `animated` is `false`.
