dd2415df73 seek & read RAM Bundle
Summary: For RAM bundling we don't want to hold the entire bundle in memory as that approach doesn't scale. Instead we want to seek and read individual sections as they're required. This rev does that by detecting the type of bundle we're dealing with by reading the first 4 bytes of it. If we're dealing with a RAM Bundle we bail loading.

bff0b1f9d6 Use numeric module IDs for iOS RA-bundles
Summary:Use the new numeric module IDs for indexed-file random access bundles, rather than string-based module names

This still uses those IDs as strings in the table, to make this bundle format work again.

f99468de65 Sourcemaps support for RAM
Summary:This rev adds support for production sourcemaps on RAM.

When we inject a module into JSC we use the original `sourceURL` and specify the `startingLineNumber` of the module relative to a "regular" bundle. By doing so, when an error is thrown, JSC will include the provided `sourceURL` as the filename and will use the indicated `startingLineNumber` to figure out on which line the error actually occurred.

To make things a bit simpler and avoid having to deal with columns, we tweak the generated bundle so that each module starts on a new line. Since we cannot assure that each module's code will be on a single line as the minifier might break it on multiple (UglifyJS does so due to a bug on old versions of Chrome), we include on the index the line number that should be used when invoking `JSEvaluateScript`. Since the module length was not being used we replaced the placeholder we have there for the line number.

17e1ceb543 Add ability to load “unbundles” to android
Summary:
public

This adds the ability to load “unbundles” in RN android apps. Unbundles are created by invoking the packager with the `unbundle` command rather than `bundle`.

The code detects usage of an “unbundle” by checking for the existence of a specific asset.
