**Summary**
This should fix install of the metro with npm (issue #142).
We can't have both babylon@6 and babylon@7 as deps for metro package, so as jeanlauliac suggested in https://github.com/facebook/metro/issues/142#issuecomment-368217279 lets create wrapper-package `metro-babylon7` and reexport babylon@7 from it.
**Test plan**
I do manually `yarn && yarn test` - all checks passed.

By removing the class completely as well as the `TModule` type, and providing options via the `context`, we'll be able to identify clearly the inputs of the resolution algorithm, and reuse it eventually for Jest. This changeset extract one more function in this fashion. Next steps: extract the rest of the stateful code into functions, or into `ResolutionRequest`.

The cache dir name now starts with `metro-bundler-cache-` but the message still refers to `react-`.

Summary:
I think the default value for the `--source-map` option is true, although it's not defined that way explicitly. Regardless, when it's explicitly set to `false` I would expect Metro to at least listen to that. Currently that's not the case. This diff attempts to improve that situation.
Note that it's still not perfect since there are more places where sourcemaps are still being touched when this flag is `false`. It turns out adding a proper flag for this leads to a lot of cascading type problems and so I ended up with this fix instead.

**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.

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.

Summary: This changeset tweaks the prelude so as to avoid overriding `process.env` if it already exists, and add tests to verify this behavior. This is useful when a bundle is loaded in a context that already provides a global `process` somehow, ex. Electron/Node.js. We still do want to override `NODE_ENV` in that case so as to have consistency with constant inlining.

**Summary**
Metro crashed with "Allocation failed - JavaScript heap out of memory" when trying to build a project with a lot of assets. (Repro: https://github.com/fson/metro-out-of-memory, `yarn start` and open the app.)
By looking at a heap snapshot, I found out the reason was that `node-haste` was reading the contents of asset files and parsing them in search of the `providesModule` docblock field, although it should only do this for source files. I fixed this by checking that `isHaste()` evaluates to `true` before attempting to read the docblock. (`AssetModule` always returns `false` for `isHaste()`.)
**Test plan**
* Ran the [repro](https://github.com/fson/metro-out-of-memory) before the fix. It crashed with `FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory`

Summary:
This is part of the efforts to clean up and extract the resolution logic. In this diff, the haste resolution is moved as part of the main resolution function rather than having 2 separate top-level functions. The reason for doing this is that logic is duplicated otherwise, making the already complex code harder to follow still. An example of duplicated logic is the call to `isRelativeImport`, that is done both in ResolutionRequest and ModuleResolution's node resolver. In that case, we never want to use Haste. Another duplication is the redirect of requires of package/haste names. With this changeset it is done in a single place at the beginning of the algo.
This changeset causes slight changes in behaviors. For example, consider `require('Foo/')`. A lookup of `Foo` would be done in the package `browser` field for a potential redirect. With this new code, we'll only look for `Foo/` in the redirect map. My opinion is that this is for the better, as this uniformize the way it works with Node.js `node_module` packages, making resolution more predictable. We should, additionally, actively strive to get rid of trailing slashes anywhere they might be in RN as they bring no apparent technical feature, but more confusion (I might be missing context, naturally).
Next steps will be to clean up `_resolveHasteDependency` completely, removing the callsite `try..catch` in favor of saner conditionals, and enforcing Haste packages to resolve if they exist (right now if a Haste package is found but corrupted, we just continue merrily trying to resolve the module with the rest of the logic; we should hash-crash instead, same as has been done for `resolvePackage`).

Summary:
The spec doesn't say the `browser` field should actually generate a replacement for the main *file*, just that it provides an alternative main: https://github.com/defunctzombie/package-browser-field-spec#alternate-main---basic
We also don't have any test covering this behavior. Any package relying on this behavior should be fixed to have a redirection of the main *file* in addition to their `main` *field*.
This is part of an effort to cleanup the way we do redirections. Eventually this will be part of the resolution module, not `Package.js`.
