Summary:
Having a function that symbolicates any given stack trace
is convenient, e.g. in #7459
More cleanup to follow.

Summary:
Many RN devtools (inspector, source maps, etc.) rely on packager.
This refactors individual SourceCode.scriptURL parsing into one function
that will be easier to change in the future.

Summary:
See "D3291793 Symbolicate JS stacktrace using RN Packager" for the background
of why this matters. TLDR - saving tons of memory by moving symbolication from
JSC into server and cleaning up old hacks.
Before this change: a redbox causes +73MB JSC size
{F60869250}
{F60869249}
After this change: a redbox causes +1MB JSC size
{F61005061}
{F61005062}
Next step – replace JS implementation by native to show better progress and
clean up even more old APIs (ExceptionsManager.updateExceptionMessage).

Summary:

To make sourcemaps work on Hot Loading work, we'll need to be able to serve them for each module that is dynamically replaced. To do so we introduced a new parameter to the bundler, namely `entryModuleOnly` to decide whether or not to process the full dependency tree or just the module associated to the entry file. Also we need to add `//sourceMappingURL` to the HMR updates so that in case of an error the runtime retrieves the sourcemaps for the file on which an error occurred from the server.
Finally, we need to refactor a bit how we load the HMR updates into JSC. Unfortunately, if the code is eval'ed when an error is thrown, the line and column number are missing. This is a bug/missing feature in JSC. To walkaround the issue we need to eval the code on native. This adds a bit of complexity to HMR as for both platforms we'll have to have a thin module to inject code but I don't see any other alternative. when debugging this is not needed as Chrome supports sourceMappingURLs on eval'ed code

Summary:
Inline require `ExceptionsManager` dependencies which are eagerly loaded on app startup (via `setUpConsole()` which is called from `InitializeJavaScriptAppEngine.js`) even though it's necessary until an exception needs to be reported.
This can save about 30-40ms on an iOS device.

Summary: Partially fixes#3316 by addressing 16 linter warnings:
- Strings should be singlequote
- Missing semicolon
Travis build jobs 1.1 through 1.4 complete successfully. 1.5 fails through what appears to be an unrelated issue on master.

Summary: - Includes the error cookie with soft exceptions as well since they too can be updated (requires tiny Android change too)
- Passes the error cookie through instead of leaving it unused
