* Remove dependency on `org.matrix.e2e_cross_signing` unstable feature
Currently, we have some code that relies on the server declaring support for an
`unstable_feature` called `org.matrix.e2e_cross_signing`. There is nothing in
the spec that requires this, so this would make us incompatible with some
server implementations.
The features in question were added in spec v1.1, so we can test for that
instead.
* fix unit test
* Document and support the established naming convention for config opts
This change:
* Rename `ConfigOptions` to `IConfigOptions` to match code convention/style, plus move it to a dedicated file
* Update comments and surrounding documentation
* Define every single documented option (from element-web's config.md)
* Enable a linter to enforce the convention
* Invent a translation layer for a different change to use
* No attempt to fix build errors from doing this (at this stage)
* Add demo of lint rule in action
* Fix all obvious instances of SdkConfig case conflicts
* Fix tests to use SdkConfig directly
* Add docs to make unset() calling safer
* Appease the linter
* Update documentation to match snake_case_config
* Fix more instances of square brackets off SdkConfig
* Enable sentry global handlers if automaticErrorReporting is on
* Pass the exception through on session restore error
Passing the exception object itself through to the BugReportDialog means a stack trace can be correctly recorded in Sentry
