This implementation reuses as much of the Lifecycle flow as it can without causing problems. Most importantly, it requires https://github.com/matrix-org/matrix-js-sdk/pull/975 to be able to detect a soft logout and react to it. When it comes time to starting/stopping the Lifecycle, additional parameters are provided so that the auxiliary services can (re)start themselves without the client starting to sync.
The cancellation can be because of a background problem, or because the user received another verification request from the same user. The cancel function does get called, however due to the speed of our dialog handling the state ends up being lost forever. Instead of trying to de-layer dialogs, this just fastforwards the whole dialog to "cancelled" on mount if required.

We are no longer seeing this error being triggered, and are considering it fixed. As a result, the dialog can be removed to reduce the amount of dead code in the project.
Rooms which are already upgraded shouldn't be asked to upgrade. Additionally, this fixes a bug where the room upgrade dialog would stay open even after upgrading the room.
Little bit of a mix of things in this one:
* Support variable-width dialogs. Default is fixed-width as before,
only UploadConformDialog is variable-width. Controlled by a prop
to BaseDialog.
* Fixes to the cancel 'x' - scale the mask image, tweak size & colour
* Colour & boldness of dialog titles
* Align the dialog title & cancel 'x'
* Remove gap between dialog buttons & right hand side of dialog(!)
* Round corners on dialogs
* Add grey border on image preview in upload confirm dialog
* and, squeezing in slightly randomly, finish the partially renamed
ChatInviteDialog to AddressPickerDialog.
