Distributing native extensions

The obvious questions are how can we give our extensions to someone or how can we use somebody's native extension? Currently, there's no unified way for this, and we have to download extensions and compile them by ourselves. This also includes all third-party libraries that the extension is using and can't be distributed with the extension because these have to be built specifically for our platform and architecture.

There's a https://pub.dartlang.org/packages/ccompile project that looks promising and may become a universal build tool for Dart's native extensions in the future.
