* Switch to importing TypedEventEmitter from main js-sdk export
* Switch to importing js-sdk/matrix in cypress
* Remove duplicated imports
* Fix lint:js-fix to run prettier last otherwise ESLint --fix may cause a mess
* Add lint rule
* Switch to importing models/Room from main js-sdk export
* Switch to importing models/room-state & models/room-member from main js-sdk export
* Fix cypress-axe import
* Fix more imports
* Fix cypress-axe import
* Fix bad merge
* Use new `CryptoEvent.VerificationRequestReceived` event
https://github.com/matrix-org/matrix-js-sdk/pull/3514 deprecates
`CryptoEvent.VerificationRequest` in favour of
`CryptoEvent.VerificationRequestReceived`. Use the new event.
* Factor out `getDeviceCryptoInfo` function
I seem to be writing this logic several times, so let's factor it out.
* Factor out `getUserDeviceIds` function
Another utility function
* VerificationRequestToast: `getStoredDevice` -> `getDeviceCryptoInfo`
* SlashCommands: `getStoredDevice` -> `getDeviceCryptoInfo`
* MemberTile: `getStoredDevicesForUser` -> `getUserDeviceIds`
* Remove redundant mock of `getStoredDevicesForUser`
* Update references to `VerificationRequestEvent`
* Update references to `Phase`
* update references to legacy `PHASE_*` constants
* Replace `request.canAccept` with `canAcceptVerificationRequest`
* Replace `VerificationRequest` with the interface throughout
* Minor strict type fixes
* Add a couple of tests
* Use new `VerificationRequest.getQRCodeBytes()`
* Use new `VerificationRequest.otherDeviceId`
* Remove references to `VerificationRequest.channel`
* Replace references to `VerificationRequest.{requesting,receiving}UserId`
Normally these are guarded by `request.initiatedByMe` so we can trivially
replace it with `request.otherUserId` or `client.getUserId()`. In one place we
actually need to apply some logic.
* increase test coverage
* Even more test coverage
* Even more test coverage
* Use `getShowSasCallbacks()` and `getShowQrCodeCallbacks()`
... instead of type-casting
* Update method names
These methods got renamed in the js-sdk PR
* Fix strict typing errors
* Basic test for IncomingSasDialog
* Basic test for VerificationPanel
* Replace references to IGeneratedSas and ISasEvent
* Some secret references to the callbacks types
* Update references to `QrCodeEvent`, `SasEvent` and `VerificationEvent`
* Apply `strictNullChecks` to `src/components/views/room_settings/*`
* Restore tsconfig.json
* Conform more code to `strictNullChecks`
* Iterate
* Update matrix-widget-api
* Conform more code to `strictNullChecks`
