Summary:
An Ast consists of `Node` elements and the one Babel uses is specific to Babel (incompatible with Astree spec by default) so `BabelNode` seems more appropriate.
Keeping the other `ast` names for now to reduce the footprint of this diff.
Also makes sure `babel-core` properly exports the same node type as what the api returns making fixes to this type in the future easier to implement.

Summary:
This bridge pulls in the various babel things and exports them again.
In a future update this bridge will also pull in babel 7 versions of the same thing and an env var will determine which sources to use so you can switch between using babel 6 or 7 through ENV.

Summary: Tries to adress https://github.com/facebook/metro/issues/65. We need a reasonnable workaround to support modules like `moment.js` that do dynamic requires but only in some cases. By replacing the call by a function that throws, we move the exception at runtime instead of happening at compile time. We don't want to do that for non-node_modules file because they are fixable directly, while `node_modules` are not fixable by people and they get completely blocked by the error at compile time.

**Summary**
Metro reports errors using a JSON payload that has an `errors` array. Each item in this array has a `description` field. For transform errors, this field was set using the value in `error.description` -- however, JS Error objects only have a `message` field. (Grepping the Metro code, no errors (except in one test) ever get a `description` field.) This commit uses `error.message` instead of `error.description` when creating JSON payloads.
```
$ git grep description -- 'packages/**/*.js'
packages/metro/src/JSTransformer/__tests__/Transformer-test.js: babelError.description = message;
packages/metro/src/lib/formatBundlingError.js: description: string,
packages/metro/src/lib/formatBundlingError.js:): {type: string, message: string, errors: Array<{description: string}>} {
packages/metro/src/lib/formatBundlingError.js: errors: [{description: message}],
packages/metro/src/lib/formatBundlingError.js: description: error.message,
packages/metro/src/node-haste/__tests__/Module-test.js: description: "A require('foo') story",
```
**Test Plan**
Added a unit test to check that the description field is set for transform errors (with the delta bundler).
Also in a test RN app, inspected the error payload that is received by RN when there's a syntax error with HMR turned on and verified that `data.body.errors[0].description` was set.

Summary:
**Summary**
With RN 0.52, when there was a redbox due to a syntax error in a source file (with regular, non-delta bundler), the redbox would say just "No message provided". The JSON that Metro sent to RN did not include a "message" field because `JSON.stringify(error)` does not include `message`.
**Test Plan**
Add a syntax error to one of the files in RNTester's JS and load the RNTester app (from RN master). See that the redbox now says there was a transform error with the syntax error's location.
Also tested adding a syntax error with HMR enabled and saw that the error `message` field was set in the payload as expected.
Also added a Jest test to Server-test.js.

Summary:
**Summary**
Metro used to have support for "asset plugins", which allowed developers to specify arbitrary JS modules that could export a function for adding more fields to asset data objects. Some of this functionality was removed in the delta bundler work -- this PR adds it back.
**Test plan**
Made existing unit tests pass and added unit tests to test asset plugin behavior. Also tested E2E in a React Native project by adding `assetPlugin=/path/to/pluginModule` to a JS bundle URL and ensuring that the plugin ran.
