Native library support for Pub

Pub should define a layout convention for extensions with native library components (https://github.com/sam-mccall/dart-sqlite is a simple example).

Pub should be able to build the native components as part of installation, on systems with the appropriate toolchain available.

Pub should also be able to share the resulting platform-specific binary package, so that other users don't have to compile it.

We have adopted the convention of putting shared libraries in the same directory as the extension, without thinking too much about it. We also support relative paths and absolute paths.

Soon we should reevaluate where the native libs should go, thinking about deployment and security issues as well. Do you think the current solution is the right one?

.so-in-the-same-directory has been very convenient for me, easy to understand, and keeps the library directory self-contained.

I'd like to keep it, if it doesn't complicate security or pub too much.

A "Dartify" step could be nice at pull time in Pub ..

This looks very cool, Andrew. We aren't working on native extension support right now, but when we get to it, I'll take a closer look at what you have here. Thanks!

Sorry, but there's no update here.

We've been primarily focused on client-side Dart applications which (naturally) do not allow native extensions. When the larger Dart team makes a shift towards server-side applications, we'll be able to start looking into this.
