(This is the error from T233127.)
It's still somewhat unhelpfully generic because it can appear in many
situations. But at least it'll be searchable, and less ambiguous about
where the 404 happened when a user reports getting this error.

Something is causing the 'ETag' headers produced by the "public"
RESTBase (queried directly from the client) to be mangled or lost.
My theory is that some proxy or browser extension is doing that.
When we detect a bad etag when fetching the page contents, discard
the result and try querying the "private" RESTBase via the MediaWiki
API (similar to what we do on private wikis, except there we talk
directly to Parsoid instead of RESTBase). After I463a84de63, that
returns the etag as part of the payload rather than HTTP headers,
and should pass unharmed through whatever is mangling the data.
Also compare and log the two etags.

Context items can be created for specific template titles. Titles
are mapped to context items using an on-wiki message.

When saving fails for a reason we don't handle explicitly, the error
message will have HTML formatting and will respect any on-wiki
overridden messages, rather than being plain text generic message.
Extensions providing custom SaveErrorHandlers may need to be updated.
The only one in Gerrit that requires a fix is TitleBlacklist:
Ibeae79c95557a7af699716c9d921f34c310bee6d.
* Remove handling for errors returned in .visualeditoredit.edit.info
rather than .errors (.error in old format). AFAIK this is only used
by some extensions, it is probably incorrect to do (T229539) and all
extensions I know of that do this (AbuseFilter, SpamBlacklist,
ConfirmEdit) have custom SaveErrorHandlers.
* Remove custom error messages for 'readonly' (identical to API
response) and for 'hookaborted' (very unhelpful and there is a
chance that the API response is better, if the extension causing
this error generates any error message).
* Add a silly shim for MobileFrontend integration, because we allow it
to handle error responses, and it expects them in the old format.
This is probably subtly wrong in many ways, but MobileFrontend code
only uses this for logging, so it shouldn't explode. In the future
we will hopefully change it to use errorformat=html (T228897#5366960).
