Now that we're pointing at `src/` for tests, we can stop trying to load source maps from random places. With this dependency used, source maps are off by a few lines.
The earlier commit, d3ce0cb82f, has most of the juicy details on this. In addition to d3ce's changes, we also:
* Use `TestClient` in many integration tests due to subtle behaviour changes in imports when switching to ES6. Namely the behaviour where setting the request function is less reliable in the way we did it, but `TestClient` is very reliable.
* We now use the Olm loader more often to avoid having to maintain so much duplicate code. This makes the imports slightly easier to read.
* Support .well-known autodiscovery in the js-sdk
It's much more useful here than in the react-sdk as it can be reused by more applications. This is also required to make the react-sdk a little easier to manage .well-known lookups as soon it'll be doing it in several places.
Automatic discovery is an abstract concept in the spec and could include more than .well-known in the future, so this is made to be generic enough to support future mechanisms and other resources to discover. There's also a ton of comments (more than normally needed) as people may wish to use this as a reference in their own implementation and it doesn't hurt to explain what everything is doing.
Many of the functions are air lifted from the react-sdk and modified to work within the confines of the js-sdk.
* Swap out uglify-js for uglify-es
So we can start using ES6 dependencies without figuring out how to update babel.
`uglify-es` is compatible with `uglify-js@3` (we were using `@2`) , which is why the same command is used. This commit includes changes to the command line to make the thing run the same as before too.
* Appease the linter
* Appease the linter some more
* Appease the linter: the tiebreaker
* Appease the linter yet again
* Switch to using the already available URL libraries
* Remove excess logging
