`OnClosing` is only implemented in WASM at this time.
`OnError` isn't tested, but should work as follows the existing
code.

Fixes#515
This includes a few small and closely related changes:
1. All occurrences of the build tag `+build js` have been changed to the
more precise `+build js,wasm`. This will exclude the files from being
included by third-party compilers like GopherJS, with which they are
incompatible.
2. Some files which are incompatible with JavaScript/Wasm now have the
correct build tag (`+build -js`) so they will be excluded from Wasm
builds.
3. Some configuration options which are incompatible with
JavaScript/Wasm (or at least the current bindings) will now no longer
appear in Wasm builds. This meant creating new files with new struct
definitions and the appropriate build tags.
The tests are run in a Node.js environment, and this does not include
any browser tests. This requires the wrtc package from npm as well as a
shim which adds portions of the WebRTC API to the global scope.
Some tests introduced here can be combined when differences between the
Go API and the WASM bindings are addressed and as missing features are
added to the WASM bindings.
We can and should add more tests in the future to improve test coverage.
This should be considered the minimum number of tests reuqired to ensure
basic functionality is working.
Resolves#478. Adds minimal JavaScript/WASM bindings. This makes it
possible to compile core parts of pions/webrtc to WASM and run it in the
browser. Only data channels are supported for now and there is
limited/no support for certificates and credentials.
