Summary:
This replaces `async/queue` with a hand-rolled queue that does not yield to the event loop if a unit of work can be run synchronously.
Anecdotally, this leads to a > 11x speedup for the graph traversal when all data is available synchronously, e.g. from an in-memory cache.

Summary: Changes `GraphFn` to return a promise rather than taking a callback. This is more in line with call sites, which so far have been using `denodeify`.

Summary:
Changes `LoadFn` to be synchronous or return a promise, and `ResolveFn` to be synchronsous.
This makes for a nicer API, without losing the property of not yielding to the event loop for synchronous work.

Summary: When running with node 8, the babel plugins `async-to-generator` and `syntax-trailing-function-commas` are unnecessary. Removing them makes runtime transpilation faster, and the resulting code is closer to the original (useful with debugging: less unmapped code areas, better breakpoint support, less renamed variables).

Summary:
This copies the basic loading mechanism and default config from the RN local cli into Metro and exposes it under `metro-bundler`, and switches internal scripts over to it.
davidaurelio: I changed the packager-worker-for-buck to hardcode the rn.cli file, like we do in other files. I would like to pull the "find" mechanism that traverses up to find a config into Metro at some point, but for now I'd prefer to keep it lean until we need it. Let me know if that doesn't work for you.
The next diff will switch the RN cli over to these functions also.

Summary: As a first step in defining a new public API and CLI for Metro, I'd like to pull the generally useful pieces from the RN cli into Metro. This diff makes it as a non-breaking change (so we don't have to bump the version of Metro for RN) by updating only the imports outside of the react-native-github folder.

Summary:
This diff renames all the stragglers in comments and strings from variations of "packager" to "Metro Bundler". I did one of three:
* Rename "packager" to "Metro Bundler"
* Rename "react-native-packager" to "Metro Bundler"
* Remove "packager" when code inside of Metro implies that it's about Metro
I also removed `Glossary.md` because it is unmaintained and very old. mjesun is currently starting to write documentation for Metro which will supersede whatever was there before.
